well, the movie like most hollywood pictures, was finished before the trailer. yeah i used TDK music in the trailer. but not in the actual film, as the soundtrack was NOT released yet in june.
yes i suppose if you watched the trailer you could get a glimpse of joker's character.
if you honestly believe the two characters look alike you don't have eyes. im sorry but come on, they are clowns. white make-up is essential. so is lip stick dumb ass. the clothes are exact opposite, as is the hair. the lip licking was not intended. everyone does it. and oh man, holding a knife and flipping it really does prove it's a rip off.
we made this without even thinking about TDK. as for your "version", i bet you've never made a film, worked on a set, directed anything, won any awards, or been entered in any festivals.
