'Jungle'

As a bonus, here's one survival film that hasn't been released yet. Based on the memoir by Yossi Ghinsberg, an Israeli adventurer, "Jungle" will tell the true story of one man's three-week survival in the remote Bolivian rainforest.

Helmed by Australian director Greg McLean, the movie will also star American actor Kevin Bacon taking on the role of an Austrian guide named Karl. While still in production, Ghinsberg says the film will undoubtedly have an impact on all who see it.

Ghinsberg told From The Grapevine: "It is very moving and a great privilege, and the story is a great true story that deserves to be told to masses. It can touch many hearts and make a difference in many lives."
