I honestly don't get why Nolan's Batman can't be brought into a Justice League movie. Yeah, he's grounded in realism and people say Nolan's Batman couldn't fit into the larger DCU with all of the fantastical characters like Superman, but...isn't it that way in the comics? To me, one of the beauties of the DCU has always been that a "low" fantasy character like Batman has been allowed to coexist with "high" fantasy characters like Superman and GL. IMO, you'd just need to tone down some of those "high-fantasy" elements for a movie. One of Green Lantern's weaknesses was that it appeared too cartoonish with all the CGI utilized. I think that could have been fixed if they had changed that by having the Guardians be portrayed by live actors, not done by CGI and had some of the Oan environment actually be real sets, not CGI constructed landscapes. I mean, even in the comics, when a GL appears before the Guardians, they appear in a closed metallic "board-room", not a mountain citadel. It appears that Marvel tends to tone down their fantastical elements from the comics, while DC believes that they should make them more grandiose (at least with GL).
I think if Man of Steel is as good as I hope (knock on wood), then DC should really consider combining Nolan's Batman with Nolan and Snyder's Superman. Potential JLA and World's Finest movies would be incredible.
What do you guys think? Can't we use Nolan's Batman in a JLA or World's Finest movie?
P.S. I don't know if there's thread on this topic already. sorry if there is.
