OMG , I can't believe that I forgot Beautiful Thing.
Also, Le Placard ( the closet) a wonderful French farce, yes , I know the main character is straight and only pretending to be go because he is sure that he is going to be made redundant and thinks that his best bet to avoid it is to be able to play the 'homophobia' card.
Last but not least "Aimee and Jaguar", yes , I know it is a lesbian film, but probably the best LGBT film I have ever seen.
