Survival movies are great not only for some entertainment, but you can also learn a lot from them, especially if they are made based on a true story. You can find most of these movies on Netflix, Disney plus, Amazon Prime Video, and some even on Apple TV.
The best survival movies are, Cast Away, 127 Hours, Touching the Void, Alive, A Cry in the Wild, All Is Lost, The Revenant, Everest, Jeremiah Johnson, Into the wild, Desierto, The Flight of the Phoenix, The Snow Walker, Against The Sun, The Grey, Kon-Tiki, The Way Back and Lord of the Flies.
My personal preference in terms of survival movies is solo survival scenarios, as in real life SHTF scenarios the probability that you will have to rely only on yourself is fairly high. You can view a lot of survivalists movies on Amazon Prime, Click here to check it out on Amazon
One of my favorite hobbies is watching movies, especially survival movies. During the past several years I have watched literally hundreds of survival movies, my favorites are the ones that are based on a true story and in a realistic SHTF scenario. 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 these movies is that no matter what you are preparing for, always 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 produced 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 into the ocean. 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 on 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.

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, they have listened to a short broadcast which was calling 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.
The biggest problem was that the tail end 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.

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 safe 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” due to 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.

This is the true story of Christopher McCandless played by Emile Hirsch and co-produced by Sean Penn. In 1992 Christopher McCandless decided that he wants to be a true survivalist and live off the land, so he hitchhiked to Alaska. His survival journey starts in a remote location called Stampede Trail which is notoriously difficult even for experienced hikers and survivalists. One of the biggest obstacles in this area is the Teklanika river which doesn’t have a bridge even today.
McCandless manages to cross the river in a shallow area as the flow of water was limited due to the summer temperatures. McCandless’s goal was to walk all the way to the Bering Sea, all the while he would live off the land and writing in his journal. During his journey, he finds an abandoned bus that was previously used by workers in the forest industry but it has been long abandoned since.
McCandless sets up camp in the bus and forages and explores the surrounding areas. He mostly hunted for small game but on one occasion he managed to kill a moose, he had knowledge on how to preserve meat but the moose meat has started to rot before he could preserve it. After spending about two months in the wild he decided to go back to civilization, his efforts of getting back were blocked by the Teklanika river which has increased in volume and he could no longer cross it.
He eventually headed back to the bus and after several weeks he started feeling the effects of malnourishment as he couldn’t find enough food to eat. Luckily he had a book with the local edible plants and he used it to forage but at one instance he misidentified a plant and he ate something poisonous. In addition to starving to death, he has also poisoned himself by accident, his body was so weak that he could hardly stand up.
During this time he was still writing in his diary and on the last written page of his diary he comes at ease that he is dying and he thanks God that he had a good life and God bless to all.
UPDATE: The actual bus has been removed from the trail by the local authorities.

The Flight of the Phoenix
- Director: Robert Aldrich

- Stars: James Stewart, Richard Attenborough, Peter Finch
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 biggest problem was the lack of 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 for 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 to take her 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 at 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 ends 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 any ways of getting food for the winter. Out of an act of desperation and in order to ensure Kanaalaq will survive the winter her mother has wandered into the wilderness where she eventually died. One morning during their journey Charlie wakes up and doesn’t find Kanaalaq, he follows her footprints which lead into the wilderness and she has done what her mother has done, sacrificing herself for somebody else.

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 abandons 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 that 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.

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 learns that the prisoner is saying that he has a plan to escape to every new prisoner, he doesn’t really have any plan, he is just dreaming of escaping.
Siberian gulags were especially difficult to escape from, tight security and patrols with vicious guard dogs that were bred to fight off wolves and even bears.

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.
On the first night the group heads out to search for firewood, one of the prisoners can’t 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.

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 survival movies, some are based on true life events while others are fiction. Most older survival 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 movies first and only then watch the new versions.
