With Gal Gadot officially cast as Wonder Woman, the cast on Man of Steel 2 is increasing, with new details on a villain role.

Amid the hype of Gadot's casting as Wonder Woman, Variety also reported a detail about who Warner Bros. is looking to cast for the villain role in Man of Steel 2, a.k.a. Batman vs. Superman.

Callan Mulvey (Zero Dark Thirty, 300: Rise of the Empire) is reportedly the main choice to play the unnamed villain, according to Variety.

The New Zealand-born actor could be playing Lex Luthor, the infamous supervillain and nemesis to Superman or potentially Doomsday, another villain rumored to be in the film.

There are also rumors spreading that the villain Metallo will be the primary antagonist in the film, according to ThinkMcFlyThink. Metallo is a cyborg with a metallic body, allowing him to forego eating, sleeping and breathing.
