One of my favourite movies is 'Into the Wild'. Also,the original book is a good read.

The book has the same name 'Into the Wild

by Jon Krakauer. I have read many Jack London novels too.

Into the Wild is a 2007 American biographical adventure drama film written, co-produced, and directed by Sean Penn. It is an adaptation of the 1996 non-fiction book of the same name written by Jon Krakauer and tells the story of Christopher McCandless ("Alexander Supertramp"), a man who hiked across North America into the Alaskan wilderness in the early 1990s. The film stars Emile Hirsch as McCandless, Marcia Gay Harden as his mother, William Hurt as his father, Jena Malone, Catherine Keener, Brian H. Dierker, Vince Vaughn, Kristen Stewart, and Hal Holbrook.
