Why It Was Cancelled

 * 2) Christopher Reeve and the rest of the cast all refused to work on another Superman film after working on Superman IV: The Quest For Peace.
 * 3) Warner Bros. didn't want to get into another budget dispute with Cannon Pictures.
 * 4) Following a string of other failures, Cannon Films was losing money and went out of business in 1994.
 * 5) Warner Bros. did not want Cannon Films to get the rights of the Superman property if it were rebooted or got a new sequel. Thankfully, that never happened since Cannon went out of business.
