Best survivalist movies
One of my favorite hobbies is watching movies, especially survivalist movies. During the past several years I have watched literally hundreds of survivalist movies, my favorites are the ones that are based on a true story and in a realistic SHTF scenario, so no zombie movies in my list. Most of these movies give a good idea of what could happen in different SHTF scenarios, from personal SHTF scenarios to global SHTF scenarios.
You might also notice that most of these movies are older productions except a few, as there are very few good survivalist movies produced in the past 4-5 years. What I have learned after watching thee movies is that no matter what you are preparing for, allways expect the worst and hope for the best. The movies which are inspired by real-life events often show how a normal day can spiral out of control and they end up fighting for their survival.

One of my favorite survivalist movies is Cast away with Tom Hanks produce in 2000. The flight of Tom Hanks experiences severe turbulence while traveling from Moscow to New York, the turbulence gets so bad that the pilots have to ditch the airplane. They end up crashing near a deserted island, the only survivor is Tom Hanks and all he has are the clothes on his back and some random items washed up on the shore.
If you have already read my article on Top 10 things to take on a desert island, you already have a good idea for what to expect for in a desert island. One of the most important aspects which Cast Away depicts is the psychological effects of being stranded away all by yourself. Battling loneliness he ends up talking to a handball which he names Wilson, after the first few weeks of struggle Tom Hanks becomes familiar with the surroundings and he is able to feed himself.
In an act of desperation, he makes a makeshift life raft and he sets sail towards the shipping lanes, after a few weeks he is found by a cargo ship and rescued.

The plot is about a plane crash in the Andes mountains, during severe turbulence the pilots lose control over the plane and eventually crash. Several passengers survive the crash although some are seriously injured. Due to the extreme cold environment, they spend the night in the fuselage of the airplane, on the second day they try to search for any food and water. All they find is some wine and chocolates.
After a couple of days, the survivors see a plane flying nearby and some of them claimed that they have seen the plane signaling with its wings. In a euphoric state, they eat all the remaining rations which understandably upsets some of the other survivors. On the 9’th day, they have managed to start the radio and to their horror, there was a broadcast to the search and rescue team to call off the search.
Some of the remaining survivors decided to go and find the tail section of the plane which broke off mid-flight as this might contain batteries needed for the radio so they could signal for help. Although in my opinion, they could have used other signaling methods which could be seen from miles away, if you want to know which signaling methods are best for this situation to check out my article What is the international emergency signal for distress.
The biggest problem was that the tail and could be miles away and they had no food or water, the only way they could survive this journey would be if they would eat the dead. After finding the tail section of the plain they still could not make it operational as it was damaged, at this point two of the survivors decided to go and search for help. The other survivors at the plane crash site all had to resort to cannibalism to survive but eventually, the 2 man party found civilization and managed to rescue the remaining survivors.

Based on a true story, Everest is about a group o mountain climbers, some of them are professional mountain climbers but there are some ordinary people as well like a postman who hopes that he will be the first postman on top of the Everest. As Everest is becoming ever popular with mountain climbers there are a lot of climbing parties at the base camp, the team knows that the hard part will not be the climb but the actual descent.
There are a lot of narrow passages where it is safer to travel but if they would come across a party of mountain climbers going the other way it would be extremely difficult as there is not enough room for two people to even fit there. The climbing party decides to head out early in an attempt to bypass the “rush hour” produced by the other climbers. The team faces several challenges like climbing over deep crevasses and even an avalanche.
Once they reach the top of Everest they are overjoyed and after a brief celebration they decide to descent, however, a massive storm hits them making the descent extremely dangerous. Some of the climbers are so exhausted that they would outright give up, but their teammates will not leave them behind.

The Flight of the Phoenix
- Director: Robert Aldrich

When you search for this movie you will find two versions of it the one from 1965 and the one from 2004. The 2004 version of the movie is a remake of the 1965 version but I still prefer the 1965 version more. The plot is about a group of people traveling home with an airplane, when a sandstorm clogs up the engines of the aircraft and the airplane crashes, killing two of the passengers and injuring one of them.
Luckily they have plenty of figs on board as this was being returned back to the company as nobody liked them. Their big problem was with water as even if they would ration the water it would only last for 10 days, oh and I forgot to mention that they have crashed in a desert. Two of the survivors come up with a plan to go and search help in a remote oasis by only traveling at night and sleeping during the day.
The two men set off and they are being followed by another survivor which ends up dying of dehydration. After a couple of days, only one of the survivors manages to get back to the crash site and he is badly dehydrated. During this time one of the survivors comes up with a plan to make a new plane from the wreckage of the old one, most survivors think that this is an absurd idea but they are finally convinced as it will be a morale booster and they should rather do something to save themselves than to wait for the search and rescue team.
When the new plane has been built they name it “The Phoenix” which is a story about a dead bird raising back from its ashes and flying away. Before they can test the plane they notice a local Arab rebel outpost nearby and two survivors decide to go and ask them for help, but they get killed by the rebels instead. During this time the “engineer” which came up with the plans of building the new plane is found out that he isn’t a real engineer and he mainly builds model airplanes, basically toys.
The group has serious doubts about the successful launch of the plane but after several attempts into starting it, the plane finally starts and the group manages to fly away.

Usually, survival movies are either set in the mountains or in the desert, this one is different as it is set in the tundra. While at first I never considered the tundra to be a harsh and unforgiving environment this move shows that in fact, it is one of the most dangerous environments from them all. The story begins with a WW2 veteran bomber pilot named Charlie, which has been piloting a small plane across the arctic ocean to supply Inuit settlements.
While in one of these Inuit settlements Charlie has bee approached by a group of Inuits asking for help. They had a sick woman with them named Kanaalaq and she needed urgent medical help. Charlie didn’t want to agree as the town with the hospital would be way off his route, but the Inuits pay him with a couple of walrus tusks and he agrees. While in the air the engine of the plane starts to backfire, and eventually it stops functioning altogether.
Charlie has to crash land in the tundra, both of them survive but Kanaalaq is sick and she would need immediate medical attention. Charlie knows that rescue will not come as they are off course by hundreds of miles. He considers Kanaalaq a burden and decided to take his chances of finding help alone. Charlie doesn’t have any survival knowledge and during his journey one day when he wakes up he is surrounded by a swarm of mosquitoes.
In an attempt to get away from their bites he starts running barefoot over the vulcanic ruck which cuts through his feet. In serious pain, he is eventually found by Kanaalaq and healed with natural remedies. Charlie spots a plane flying and thinks that it is the search party, and he thinks that they should head back to the crash site as the crashed plane has probably been found. When they arrive to the crash site they do not find anybody and this makes Charlie very depressed as winter is coming and they will probably not survive.
Kanaalaq knows how to live off the land and also teaches Charlie, she also knows how to hunt caribou and the pair eventually end up killing 3 caribous which should be enough food for both of them to last the entire winter. The two decide that their best hope of surviving would be an Inuit camp which is around 100 miles away so they set up for the long and hard journey. Kanaalaq’s condition is starting to deteriorate fast and Charlie has to carry her.
One night Kanaalaq tells Charlie that during a time of famine in their Inuit camp that her father has died in a snowstorm, leaving her and her mother without anyways on getting food for the winter. Out of an act of desperation and in order to ensure Kanaalaq will survive the winter here mother has wandered into the wilderness where she eventually died. One morning during their journey Charlie wakes up and doesn’t find Kanaalaq, she follows here footprints which lead into the wilderness and she has done what her mother has done, sacrificing herself for somebody else.

In addition to not having any food and water, they also have to worry about being captured by the Japanese.

This story happens in a remote part of Alaska, with John Ottway who is hired by the oil company to protect the oil workers from attacks of predators mainly wolves. This is by far one of the best wilderness survival movies, as it has the fight for food, fighting against predators and the forces of nature. As the contract for the oil workers comes to an end so does John’s contract and they travel by plane towards civilization. During the flight, the engines start to stall and the plane eventually crashes, only one member of the oil workers is seriously injured and eventually dies.
The local wolf pack is becoming increasingly bold and approaches the camp, while most oil workers would want to stay at the crash site as that would be their best hope for being rescued, John argues that they are in the wolf packs hunting territory and it will be only a matter of time till they will be attacked. The team abandoned the crash site and attempt to get to safety during wintertime, in a wolf-infested area.
One by one the oil workers die, killed either by the wolves or by the cold. Their main goal was to get as far as possible from the hunting territory of the wolves, but as the attacks from the wolves become ever more present they come to a realization that they are actually getting deeper into their territory. Eventually when only two survivors remain, one of them is John they find the wolves den which is guarded by the Alpha wolf.

This movie is based on the real-life Kon-Tiki experiment from 1947 and this is the only movie which is not in English so you will need subtitles for this, but if you can bear with it I promise you that this is one of the best survival movies. Unlike most survival movies which start with some kind of catastrophic accident, this one starts with a man and his simple idea to prove everybody wrong. The story is about the journey of Thor Heyerdahl, who wanted to prove that South American people have sailed and landed in Polynesia even before America has been discovered by Colombus.
His main goal was to use only ancient sailing techniques and a balsa wood raft which were used around the year 500. Thor Heyerdahl set up a crew of 5 people and set sail towards Polynesia, the entire movie is about them surviving storms, sharks, lack of food and dehydration.

This is one of the best survival movies on Netflix, the movie is set in ww2 where the protagonist called Janusz Wieszczek is sentenced by the KGB to a Russian gulag in Siberia. Once he gets to the gulag he is immediately approached by a fellow prisoner who claims he has a plan to escape. In the following days Janusz plots with this prisoner on how to escape, but his hopes of escaping become shattered once he learned that the prisoner is saying that he has a plan to escape to every new prisoner, he doesn’t really have any plan, he just fantasies of escaping.
Siberian gulags were especially difficult to escape from, there was tight security and patrols with vicious guard dogs which were bred to fight off wolves and even bears. Nonetheless, Janusz decided that he will escape and face the wilderness on his own, but some inmates also want to join and after some deliberating, he welcomes them to join him in the escape. The group eventually escapes from the prison on a cold night, the prison alarms have been set off but luckily the search for them was brief as nobody thought they could survive in the harsh wilderness.
In the first night the group heads out to search for firewood, one of the prisoners cannot find his way back and he is later found frozen hugging the firewood. The group’s main goal was to reach Mongolia which was not a communist country, but the journey would be long and dangerous. One of the main landmarks they were searching for was lake Baikal and eventually, they make it there, thus they knew they were on the right track.
During their journey, they come across a polish woman which joins them as she was also trying to escape from the country. Once they reach the border of Mongolia one of the prisoners who was a career criminal and an avid communist decides to go back as there is nothing waiting from him in Mongolia.

Lord of the Flies

- Writers: William Golding, Jay Presson Allen
- Stars: Balthazar Getty, Chris Furrh, Danuel Pipoly
This is by far one of the most famous survivalist movies, the main difference between this movie and other survivalist movies is that most of the characters are actually children. The plot starts with 24 children who are in the military academy somewhere in the Pacific. They were heading home to the US with an airplane when they suddenly crash near a deserted island. The only adult which was the pilot is seriously injured.
Luckily none of the children are injured, and they quickly find a nearby source of fresh water. The older boys decide that they have to make a decision who will be their leader, after a “democratic” election between Ralph ( the normal one ) and Jack ( the sociopath ) and it is eventually won by Jack. Jack as the newly appointed leader decides to take away one of the other kid’s glasses to use it for starting a fire to signal to potential rescuers.
The group was hunting and foraging and it was peace for a while, in one day the pilot having a delirious episode walks off into the jungle. When the children approach the cave and they hear the sounds of agony of the pilot they think that a monster lives in the cave. One of the children sees the pilot but mistakes him for the monster and stabs him. After the following days, heated arguments are kindling between Jack and Ralph as Jack has left the permanent signaling fire unattended which a passing by plane would have been able to see.
One of the children finds a glow stick and decided to explore the cave, he there finds the body of the pilot. He rushes out of the cave flailing the glowstick and running towards the others, but one of the other children confuses him with the monster and stabs him to death. Ralph is extremely upset by it and he and his friend called “Piggy” are confronting Jacks “people” when one of them dislodges a boulder which ends up killing Piggy.
Ralph realizing that they have all gone mad makes a run for it and the other children are chasing him through the jungle with spears and knives. When Ralph makes it to the shore he finds a US officer which came to shore as he has seen the signaling fire and the situation calms down.
There are literally hundreds of survivalist movies, some are based on true life events while others are fiction. Most older survivalist movies have a new version produced after 2000, however, you might find some inconsistencies in these as the new producers will try to add their own unique spin to them and sometimes they embellish so much that it becomes basically a new movie. My recommendation is to check out the older versions of these survivalist movies first and only then watch the new versions.
