If it's crap ... We'll tell you
This can include movies based on real people like the films, Gandhi or W. or it can be events that have happened in history like Titanic or Black Hawk Down.
My favorite has to be David Fincher's Zodiac. Great performances, fantastic cinematography, interesting subject material and a great stylistic way of having the events played out. As well as awesome song selections.
I don't have an absolute favorite but some of them(off the top of my head) are 127 Hours, The Last King of Scotland, Frost/Nixon, Malcom X, and Ray.
Temple Grandin (tv movie)
it would either be Ed Wood or The Aviator
This movie is really inspiring! everytime I watch it i will tell me not to give up.
though many people criticize this movie for the actress' exaggerating acting, i still love her very much!
Comical exaggeration and changes in truth aside...
Ed Wood. Hands down.
