Since we're talking movies, I'll throw in a handful of movie titles that I find inspirational and /or uplifting as well:

Rocky, Rocky II, Rocky III, Rocky IV, Rocky Balboa

Vision Quest

Tin Cup

The Pursuit of Happyness

The Social Network

Rad

Hackers

Wargames

Iron Man

The Man Who Knew Infinity - based on the book of the same name, which I also recommend.
