Just when Bryan Cranston thought he could grow his hair back, turns out he won’t be able to because he has been cast as Lex Luthor in the upcoming DC Comic movies including the Man of Steel sequel. According to
Cosmic Book News he will play Lex Luthor in at least 6 movies, and that number can go as high as 10 for now.
So at this rate he should just get it lasered off, so he won’t have to worry about shaving it every day.
