Why would you want to do that? This film is a start of an all new series which does not have any continuity ties with the previous four films from the 1989-1997 series. I think you'd just be wasting your time by trying to tie this new start into the last thereby reducing the efforts of Mr. Nolan. It'd also help if people didn't think that Batman Begins is a "prequel" and start knowing it's a whole new series. Just wish that this would get into peoples heads. What's in the 1989-1997 series I think you can futz around with all you want but until the new series has established itself as a trilogy first then I'd support you in doing this. Other than that I just think it's futile. Sorry for being negative but this kinda stuff just irks me. I apologise.
