I've watched League of Their Own with my daughters a bunch of times. Also, The Longest Yard (the original version with Ray Nitschke) was a super movie. Also the movie about the QB with the little girl starring the Rock was good (I can't recall the title), and the Will Ferrell movie about a pro basketball team in the old ABA. Also the football movie, Necessary Roughness and of course, the Major League movies with Bob Uecker.
