Castle fans, you do not want to miss tonight's episode. In "Recoil," Detective Kate Beckett is going to throw down with the man ultimately responsible for her mother's murder - Senator William Bracken, played by Jack Coleman. The actor recently chatted with BFTV about what it's like to play the person behind one of Castle's biggest plotlines, and going head-to-head with his former Heroes co-star Stana Katic.

"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."

Before signing on to play Bracken, Coleman had seen Castle and was aware of the mystery surrounding Beckett's mother, but he had to uncover the full extent of his character's misdeeds. "I knew the story but I certainly had not seen all of it," he said. "They very kindly sent me an hour-long DVD of all these scenes edited together that were pertinent to the death of Beckett's mother. It was incredibly helpful."

If you enjoyed Beckett's first confrontation with Bracken, Coleman teased even more fireworks in tonight's episode. "This episode in particular was incredible amount of fun because every single scene was just loaded with psychological impact," he said. "Stana [Katic] is just so great and she's so good in this part. The great joy in this episode for me was doing all these things with Stana - she and I know each other from Heroes and we have so much fun together.

"The first time we worked together [in "After the Storm"], when she finally got to get it all out," he explained, "the scene where she ends up hitting me in the face with a gun, she was screaming and she was crying, and it was great for me because it kind of landed me in this place of what [her] character has been going through.

"She's Ahab and I'm the whale and this is her quest," he continued, "and then when she's right there where she sort of wanted to be, she sort of then has to wrestle with 'What do I do now?' I can have her killed and she could probably have me killed. They really gave this guy his teeth in this episode and every single moment that these two are on screen together is just loaded with psychological drama."

"What makes a good villain is kind of his effect upon the hero, which is what I think is so much fun about this character in this show. He has just rocked her world so badly by killing her mother," Coleman explained. "The audience has been taking this journey with Kate Beckett all this time, [and] I think they're going to be on the edge of their seats."

Castle fans are certainly hoping that Beckett takes Bracken down, and asked if he has a preference for the way he'd like to exit, "There are so many ways to go out that can be spectacular," the actor said. "I certainly think that it would be right and just that he goes out the same way Beckett's mom went out, in an alley somewhere. I think there's a poetic justice there."

These days Coleman is known for his villainy, whether it's as Bracken or Noah Bennett in Heroes, but the actor hasn't always worn a black hat. In fact, quite the opposite. "What's funny is that for years and years, I always sort of played the good guy. From Dynasty all the way forward, I played a lot of boyfriends and husbands and sons, mostly sort of good, earnest people," he said with a laugh. "It was Heroes that kind of changed all that. Now I'm seen as a kind of murky guy who's usually got a secret and something nasty up his sleeve. That's been a great change for me. I've really enjoyed it. Bad guys are fun, especially when you look like the man next door."

Castle airs tonight at 10 PM ET/PT on ABC. You can also visit the official website.
