Smallville Cast: Where Are They Now?
13. Michael Rosenbaum
Michael Rosenbaum's seven-season run as Lex Luthor is considered the definitive version of the character for many, and upon watching him in action, it's easy to see why.
Known for his comedic personality, he returned to comedy after leaving the show, appearing in films and TV shows such as Back In The Day (which he also wrote and directed), Hit and Run and the short-lived Impastor. He also returned to the superhero world, appearing in the Marvel Cinematic Universe's Guardians of the Galaxy Vol. 2.
Though he isn't on our screens at the moment, he does host his own celebrity podcast 'Inside Of You' and fronts the band Left on the Laurel.
