I think '127 Hours' is very inspiring. It shows the human will to survive in the most extreme situation. Aron Ralston's determination to free himself is truly remarkable.
The 'Revenant' is also quite inspiring. Hugh Glass's fight for survival against all odds, including being mauled by a bear and left for dead, is a testament to the strength of the human spirit. He endures harsh weather, lack of food and water, and still manages to seek revenge. The beautiful cinematography also adds to the overall impact of the story, making it a very inspiring survival film based on true events.
Definitely 'Unbroken'. The story of Louis Zamperini is one of incredible perseverance. He survives the brutality of a Japanese prisoner - of - war camp. His ability to hold on to hope and his unbroken spirit in the face of such inhumane treatment is truly an inspiration for all. It's a film that shows that no matter how difficult the situation, the human spirit can prevail.
