PRISON BREAK’s Robert Knepper To Guest Star As ‘Clock King’ In ARROW Season 2

With Arrow going on hiatus after tonight’s mid-season finale, casting is moving forward for the rest of season two. According to TV Line, Prison Break and Heroes actor Robert Knepper has been cast as the villainous William Tockman, aka the Clock King. In this incarnation of the DC Comics foe, Tockman “earned his nickname being a brilliant criminal who plans his crimes with precision, down to the second.” The character will appear in episode 14, which also sees the return of Alex Kingston’s Dinah Lance. After this week’s highly anticipated episode, Arrow Season 2 returns January 15th on The CW.
