Personally, I'm a sucker for Sport's Flicks. Below is a list of the sport's themed films that I would consider in my top 100 list of all time:
Field of Dreams
The Greatest Game Ever Played
We Are Marshall
However, there is one very underrated film that I enjoyed more than any other. And that film is "For Love of the Game". There's something about this movie that just gets me every time. I absolutely loved it.
sadly I haven't seen many of the greats you guys have mentioned.
A stupid favorite of mine is "There's Something About Mary," because I'm a die hard Niner fan and a die hard Packer hater, and Mary's reason for not choosing Bret Favre made me almost stand up and cheer in the movie theater.
