Warner Bros. has narrowed down their list of contenders for Superman's leading lady to Alice Eve, Diane Kruger and Rosamund Pike, according to Variety.

The character, who would star opposite Henry Cavill's Man of Steel, hasn't yet been disclosed -- but it's not Lois Lane.

The studio is also in the midst of a search for a Superman villain. Zack Snyder is directing from a script by David S. Goyer with Christopher Nolan producing.

Production will start this summer with a December 2012 release date.
