Batman and Superman have to dress as women to keep an apartment in an all-female boarding house in this touch economic times.
Hey, now THERE'S something that would be up John Waters' alley:
SOME LIKE IT SUPER
When they end up on the run from the authorities after President Lex Luthor frames them for murder and for an oncoming Kryptonite-asteroid apocalypse, the Man of Steel and the Dark Knight go into hiding dressed as women and join up with an all-woman orchestra from the island of Themyscira...but when Batman falls for the orchestra leader Diana, he CROSS-cross-dresses as an Air Force captain trying to woo her while Superman must fend off the advances or Mr. Mxyzptlk, who doesn't recognize Big Blue in his disguise after being banished from the 5th Dimension without powers until he can prove he can get someone to actually like him. It all ends in hilarity---
Superman (falsetto, in drag): But Mxy, I keep telling you, I can't marry you...we can never have children!
Mxyzptlk (shrugs): Zod's got one he doesn't want!
Superman (desperate): I'm an alien!
Mxyzptlk: I'm an imp from the 5th Dimension!
Superman (yelling in normal voice, ripping his wig off): I'm SUPERMAN!!!
Mxyzptlk (without missing a beat): Well, nobody's perfect!
...sorry.
In all seriousness, though...I'd like to see a DECENT Kara Zor-El film. Either Supergirl or Power Girl.
