Matt Morgan, currently wrestling with TNA and a gladiator on the most recent version of American Gladiator said in a recent interview that he was in talks about possibly being cast as Doomsday on the WB show Smallville. Matt originally was trying out for another part. He was too big for the character but when they realized his size they figured he would be great for the part of Doomsday. Unfortunately that part was already cast for Season 8. They are trying to write him into Smallville's 9th season (next fall) as the Doomsday character.
This leads into Matt talking about possibly being cast in Ironman II as a villain but he can't talk anymore about it. He attributes the interest in him by casting directors to the work he's done on American Gladiators. He talks about all the great things that have happened since appearing on the show.
