(think I'll turn this into a general DC movies thread)
I hope the Batman movie isn't going to be
too early in his career, there's no real need for an origin story - I'm pretty sure Batman's origin is in "everyone knows" territory, so they'd be better off just getting on with it.
I'm not a member any comicsy forums or anything - comics online fandom is awful

- but a comparison I read somewhere was James Bond. Whenever the lead changes, they don't start his career from the beginning. He just gets on with Bondy things.
The Zero Year comics were good. It was right after Bruce started being Batman, but before he had any Robins or met most of his enemies, etc. Actually, Riddler was one of the main villains in that story, and he's going to be in The Batman, so that could be a good shout!
