why are gay men more prevalent as actors in the theatre than in movies?

So, why are gay men more prevalent as actors in the theatre than in movies? Lots of reasons, no doubt, but one that stands out is the title of that Sondheim musical: Applause. Generally speaking, straight male actors don't mind doing the same take 26 times in row in front of a bunch of bored Teamsters, as long as they ultimately get paid off in terms of money, fame, women, and power. Gay actors, in contrast, tend to place a much higher value on adulation from a live audience.
