It might go with the horrid earlier drafts and resemble the Schumacher films more than the Burton films ever did.Bump. How does this impact the 1989 Batman movie in a couple years?
That is an extensive analysis .Miller was already a big enough star to do only the projects he wanted. DKR had the impact it did because everyone knew about Batman, and it was so different from the television series. So from a cultural point of view, Miller's new work is unlikely to have that impact. However, I don't see it impacting Miller's output at all.
If DC doesn't want DKR, then Miller likely completes the projects he was working on for Marvel. He may continue on Daredevil after completing the Born Again storyline as there was supposed to be a second story drawn by Walter Simonson. He may continue to do work on DD or perhaps another series for Marvel since I doubt he'll do a Batman: Year One without having done DKR. Ultimately though, Miller releases his independent projects through Dark Horse Comics including Sin City and 300.
I don't see how not doing DKR means there is no Sin City. Miller was already big enough among comics fans to be successful. The changes are on the larger cultural front with how non-comics readers view comics, especially with possible changes to the 1989 Batman movie (which actually didn't rely on Miller's work at all, but the earlier work by Denny O'Neil/Neil Adams and Steve Englehart/Marshall Rogers) because of the perception by studio bosses as to what a comics movie should be.
