Here's a list of the best gay movies I've seen. If you have advise on other great gay movies, give me a hint in the comments field!
(I'm using a broad definition of "gay movie". Maybe I should rather have called them "queer movies", but as I have very few lesbian movies included, that would have been even worse.)
1. A room with a view
The author was gay, the director was gay, one of the main actors was gay and the main theme of the movie is that you should grab love wherever you find it. Therefore I must be allowed to call this movie - which is my favorite movie regardless of genre - a gay movie...
2. Rebel without a cause
The socalled "friendship" between the characters of James Dean and Sal Mineo (who both were queer in real life) has always been interpreted in queer terms by a hungry gay audience. And it's a beautiful movie...
3. The Birdcage
A hysterically funny movie, even if the story is borrowed elsewhere.
4. Death in Venice
A very beautiful (although slow) movie with Mahler music in the background.
5. Beautiful Thing
A feel-good-movie which was released just when I needed it.
A wonderful gay coming out-movie.
A film that does not deny itself anything - here are full-frontal sex and lots of other activities. Uncompromising and very good.
The relationship between a father/mother and son is beautifully portrayed.
One of the classics of queer cinema - and with the love of my teenage years (Rupert Graves) in an important part.
10. Another Country
Another British gay classic.
11. Mannen som elsket Yngve
A good portrayal of adolesence in Norway in the 80s.
Canadian art movie which is beautiful.
13. Patrik 1,5
Swedish adoption comedy. It is a good sign that we have moved beyond the stage where all queer movies were about coming out or about aids.
14. Hedwig and the angry inch
This musical is wild and crazy - and I'm growing more and more fond of the music.
I remember this music movie as quite nice.
16. Fucking Åmål
The Swedish youth movie that showed how life as a lesbian in a tiny Scandinavian town van be like.
17. Billy's Hollywood Screen Kiss
18. Alt om min far
A good portrayal of Esben Esther Pirelli Benestad and his family.
