The Celluloid Closet (seriously recommend it to get the gay subtexts of movies)
In and Out
Victor/Victoria
Personal Best
btw, there a ton of movies where they hint at it, and by hinting I mean it's obvious to all gay people. Examples include "Spartacus" with the deleted bath scene. And "Lawrence of Arabia," once you learn he is a flaming gay.

And "Top Gun" is just hilarious, especially with a group of friends talking over it, making fun of how obviously gay Tom Cruise and his flying buddy (obviously his lover), and that oiled-down shirtless volleyball scene... good lord. Otherwise it's not really interesting at all. It's just hilarious at how closeted everyone is, especially with the real-life rumors of Tom Cruise's sexuality, and the fact that the love interest in the movie later came out as a lesbian. :)
