Brainiac – Michael Sheen
Of all the Superman villains that haven’t been in live action films yet, Brainiac is the most obvious that needs to make that jump. He’s a twisted scientist who proves to be a huge problem for Superman on many occasions. We’d love to see him in a future sequel to Man of Steel, and hopefully played by none other than Michael Sheen. Sheen has made his fame by being PERFECT in biopics like Frost/Nixon, The Damned United, and The Queen, but has shown that he can play fictional people just as capably.
