3. Bryan Cranston
The man who can go from calm and collected to downright villainous and crazy in the next. Bryan Cranston is a top choice to play Lex Luthor and for good reason - his character on Breaking Bad is basically like a version of Lex Luthor, a man who puts on a mask he shows to the public to throw off suspicion of his criminal activities. He also rocks the bald look, and even though Zack Snyder said his version of Lex may have hair, we all know he is going to lose it sooner or later. Cranston is no stranger to playing a villain as he took on the iconic sci fi antagonist Vilos Cohaagen in 2012's Total Recall, and say what you want about that movie, but I thought he did an amazing job and was an incredibly convincing and menacing villain. He has won an Emmy three consecutive times for his role on Breaking Bad, and that should tell you just how amazing the actor really is. Whilst he is also a fan favourite to play Commisioner Jim Gordon, I do believe he would make an incredible Lex Luthor.
