I can't see Bale and Routh playing Bats/Supes in a JLA film. Would it be cool? Of course, but as noted above, it would prolly disrupt filming for both franchises. Additionally, most actors are afraid of being pegged into a role after the usual three that they sign on for, so getting them to sign on for a 4th time in a movie where they technically aren't the leads would be near impossible. Besides, as much as I love Bale as Bats (and, yes, Routh did a solid job as Supes despite the movie itself being dull) I don't think a JLA movie would suffer if two other actors took over the roles for an ensemble movie that JLA would end up being. At worst there would be comparisons, but that wouldn't stop movie goers from seeing it - only it being a sucky film could do that.
Dear, sweet Harley Kwink...I'm madly in love with you. Marry me! We can go to Canadia. Or Boston or something. It'll be grand...You know the cookies are a given. They are ALWAYS a given. You could dump me tomorrow and you'd still get the cookies. Boston..shit, wherever dyke weddings were legalized. And where better to rub their little piggie noses in how bad they suck than right on their doorstep? What are they gonna do? Be jealous of you? Stare furiously at your tah-tahs? Not willingly give you cookies, but instead begrudgingly give you their cookies? Woman, time to wake up to the powers you wield - Uschi
