There have been two movies made about the Fairchild 571 that crashed in the Argentinian Andes on October 13, 1972.
The first was a pretty low budget Mexican movie, Survive! (1976), which was not bad, though hard to find today.

The Hollywood version, Alive (1993), had a lot bigger budget, much better acting, and a lot more drama, but it feels more like a movie.

That 1993 movie version of “Alive” was pretty good; the History Channel has also done a quasi-documentary on the crash and survivors which is good. Several of the survivors did quite well after the crash: Roberto Canesa is a cardiologist in Uruguay and does the inspirational speaker for a fee bit in the US and elsewhere, as does Peraldo. The survivors got together on the 40th anniversary a couple of years ago and played the Chilean rugby team they were on the way to play in 1972 when the Andes crash occurred. Funny, Canesa ran for president of Uruguay on a conservative ticket the last time and got less than 0.1 percent of the vote; I don’t know what the problem was as he is quite charismatic and well-spoken.
