According to Comicbook.com, Fans of Supergirl were surprised earlier this month when Jon Cryer was cast as the iconic DC Comics villain Lex Luthor for an upcoming storyline on The CW series. This casting decision left many fans wondering how an actor who is best known for his comedic roles will portray the villain. During a recent episode of his Hollywood Babble-On podcast Kevin Smith teased that he knew long before the public did that Cryer was the favorite for the role, but more than that promised the show would be portraying Lex with a "dark turn".
