5) Robin’s Cameo – Batman
Tim Burton’s Batman didn’t need any help from Robin, though a few scripts tried to squeeze the character in regardless. An early draft featured an action scene where Batman chases the Joker through Gotham on a horse, and to throw the hero off his trail Joker drives through a circus. During this scene, The Flying Graysons are mid-performance when the Joker causes them to fall by setting off a bomb, leaving young Dick as the only survivor.
He swings down and helps Batman stop the car, but Joker escapes anyway. This scene would have paved the way for him to appear in a sequel and would have tied Batman and Robin closer together, since they both lost parents to the Joker. In fact, Kiefer Sutherland was initially approached for the role, but when the chase was cut for budget reasons, the cameo was taken out, too.
