6. Batman Forever

Batman Forever

Did you know that Tim Burton was originally meant to helm Batman Forever? Unfortunately, a lot of what we know about this particular comic book adaptation is based on rumours and speculation more than anything, but various reports over the years have indicated that Burton’s Batman Forever would have introduced Marlon Wayans as Robin and that both Robin Williams and Micky Dolenz were eyed for the role of The Riddler.

Billy Dee Williams meanwhile would likely have returned as Harvey Dent, becoming Two-Face in the process. The reason it never happened is because of the issues which arose with complaints from parents and marketing partners due to the violent nature of the previous films, something which saw him made a producer and the focus put on toy friendly costumes for these comic book characters.
