With the success of the THE AVENGERS movie, howabout we predict how DC would do with a JLA movie by taking another look at the individual DC equivalent characters and how well their individual movies have done or will be doing.
The Marvel/DC counterpart list below is based on characterisation rather than any superpower matchup. Like Captain American is matched to Superman because they're both boyscout-ish.:
Captain America -- Superman
Thor --- Wonder Woman
Ironman -- Batman
Black Widow -- Black Canary
Hawkeye -- Green Arrow, or Roy Harper
The Hulk -- (Character-wise, Dr. Jekyll & Mr.Hyde.....Visual-wise, Martian Manhunter)
I know many WW fans feel that each Avengers character shares a similarity to Wonder Woman, be it their mythos or some other characteristic. Like Captain America and WW share a WW2 period and an American motif, Thor and WW share a mythological background, Black Widow and WW share....etc.
Which Avenger do YOU feel would be the closest counterpart in a significant way?
