: "Smallville" (2001-2011)
Michael Rosenbaum played Lex Luthor, the son of a billionaire sent to “Smallville” to manage a fertilizer plant. He becomes fast friends with Clark Kent, but their bond deteriorates over time. Rosenbaum left the series after season seven, but returned for the finale in 2011. His portrayal of Luthor landed him on TV Guide’s 2013 list of “The 60 Nastiest Villains of All Time.” The actor is set to star in the upcoming movie “Old Days.” —XFINITY Entertainment Staff
