Batman '89 walked so that Batman Returns could run. For some reason this movie has a lower score than its predecessor on IMDB, and that's just wrong; this movie is the best Batman movie. Well... the best live action Batman movie since Batman: Mask of the Phantasm still exists.
Once upon a time, this almost was a live-action Doctor Strange movie. Not the first, that distinction goes to the made-for-TV 1978 version staring a Mr. Peter Hooten and his pornstache. But the licensing fell through and enough details were changed so that Charles Band could be credited as "based on an original idea by." Sure, why not.
