Certainly none do, or at least I would be very surprised.

I didn't see the "Wild" movie as I didn't enjoy the book. Bryson doesn't portray "normal" long distance hiking either, but at least he's entertaining! I'm looking forward to seeing this movie.

I think that requiring Hollywood to portray any topic in a totally realistic fashion would limit you to a pretty small set of movies to watch. Most things that get dramatized in movies or books are, in real life, generally (a lot) more mundane.
