I'll check out that Wild Side movie.  But, the guy who played Hedwig and directed the movie also directed Shortbus, so I'm sure that he's at least a gay drag queen from the films he's made and been in.  Plus, the fact that the person playing Hedwig is a straight up male is part of what made me more transgendered as a result.  It's the first time I've ever seen a man and thought "Man, she's attractive."
Also, I sorta..... deep down... wanna be a transsexual metal star.  Seeing a rock opera about a transsexual punk rock star.  It's my type of thing.
