Jack Coleman returns to Castle tonight as Sen. William Bracken, the man behind Beckett's mother's murder. BFTV has a new interview with Coleman, where he talks about what makes Beckett vs. Bracken so appealing and possible exits for his character.
"Anytime you get a chance to play a mythological character it's always intriguing," said Coleman, who made his first appearance in the fifth-season premiere. "When they said 'You're the guy that killed Beckett's mother,' I just thought 'How much fun is that?' It's one thing to play a bad guy - it's another to play a bad guy who's been this looming presence since the very beginning."
