How does the film The Grand Budapest Hotel relate to ​stereotypes​ ​in​ ​contemporary​ ​society?​

In the recent history of film, gay and bisexual characters have often been presented as flamboyant, extroverted, and effete and have often functioned primarily as comic relief. Or, alternatively, they have been depicted as predatory and licentious. The Coen brothers' 2016 film Hail Caesar! has been, for example, criticized by GLAAD (which until 2013 was an acronym for "Gay and Lesbian Alliance Against Defamation") in a 2017 twitter post for using "the trope of a predatory gay character blackmailing someone for sex." Even more recently, Disney has been criticized for the reported presentation of its first openly gay character in a major film, The Jungle Cruise. The character, played by actor and comedian Jack Whitehall, is reportedly presented as very camp and effete.
The main character in The Grand Budapest Hotel is the bisexual concierge, Monsieur Gustave. Gustave does to some extent conform to the stereotypes of gay and bisexual people in that he is somewhat flamboyant, and somewhat licentious, sleeping with many of the old, rich women who stay as guests at the hotel. Indeed, as he says himself, "I go to bed with all my friends." In other respects, however, the presentation of this character is much more positive, rounded, and original. He is, for example, a kind and loyal friend to the lobby boy, Zero, defending him against the soldiers who try to arrest him on the train. Monsieur Gustave is also brave, tough, and resilient. He tells Zero, for instance, that "you must never be a candy ass; you've got to prove yourself from day one."
Overall, although Monsieur Gustave does demonstrate some of the stereotypical tropes associated with gay and bisexual characters in film, for the most part he is, I think, a character who challenges some of the most derogatory stereotypes. He is brave and stands up for himself and others, rather than being effete and effeminate. The fact that he sleeps with lots of people is also presented not so much as licentiousness, but rather as kindness. Monsieur Gustave is also not presented as a figure of comic relief. We laugh with him because of his charm and his wit but, importantly, not at him. He is tremendously likable and admirable. He is also an individual and a character in his own right, rather than a character depending on lazy stereotypes.
