Just in time before the hit Fox series Prison Break goes off the air, William will appear in a couple episodes. The last two, to be specific. (No word if they’ll be run separately or scrunched together.)  The series is on hiatus and will resume airing its fourth and final season on April 17 (William’s birthday.  Fate?  You be the judge.).  William’s episodes should run about mid-May. And in a show full of thugs and criminals, William plays — surprise — an FBI agent (name of Chris Franco). Trivia: It was ten years ago that William last worked with the show’s co-lead, Dominic Purcell, in…anyone?  anyone?… Mission: Impossible 2.
