the way i read it was that warner were the ones that wanted dicaprio for riddler. yeah, it's hard to follow up ledger's joker with riddler. even if they had gone with arkham city's riddler which was just outstanding.
i wish they would make a young avengers show or animated film, especially if it was handled right. however, they probably wouldn't because some jerks out there would make a fuss about wiccan and hulkling or something.
Nolan said that he wanted to challenge Batman on a different level than the Joker. Begins was Batman being challenged on a 'fear' level, Dark Knight was him being challenged on a 'code/psychological' level, Rises was him being challenged on a 'physical' level. He said that they had yet to have someone who could go up against Batman head-to-head. Riddler was too similar to the Joker.
Another great video. CGC comics can sell for a pretty penny. I liked Tony's expression when he mentioned John Romita Jr.'s art. I think that there will be a spike in CGC comics because of the popularity of digital comics.
@GBrutality: That's interesting. Thanks for the info.
