Kevin Costner, an oil removal machine salesman and frontman for the country-rock outfit Kevin Costner & Modern West, is reportedly being considered for a part in Zack Snyder's upcoming Superman reboot. Deadline doesn't have much more in the way of concrete information, only describing the part as "a key role" that those involved have a "heightened interest" for Costner to take. The Costner brand is on the rise! But what might the key role be? Pa Kent? Perry White? Marlon Brando's head? Green Arrow, assuming he can still fit into his Robin Hood outfit? Some kind of baseball guy? Make your guesses.
