"Henry Cavill was recently set in the Man of Steel role," says Deadline's Mike Fleming. "I'm not exactly sure what role Costner is likely to play, but he has certainly been in good guy mode lately. Beyond his performance in the John Wells-directed The Company Men, Costner surfaced as an unlikely hero in aiding the cleanup in the Gulf of Mexico oil spill. British Petroleum purchased over 30 centrifuge machines which separate oil from water, technology that was developed with a reported $24 million in funding by the actor over 15 years."
Bottom line is that at this point we have no idea of Costner is being considered in the role of hero or villain for the film. Any thoughts on what character he would be suitable for within the Superman mythos?
