Three months of grisly murders will come to an end Saturday when Harper's Island wraps up with a two-hour finale (9 pm/ET, CBS) that will be rife with "even bigger twists and turns," Matt Barr, who plays Sully, tells TVGuide.com. John Wakefield's accomplice will be disclosed, as will his mystery child. But those two aren't necessarily one and the same. "His kid could: One, be aware, or two, not even be aware that he or she is his kid." See what else the actor had to say about the final bloodbath, why there should be a Harper's prequel and the value of loving a blow-up doll.
TVGuide.com: There are some theories floating around that Sully is Wakefield's son because you and Callum Keith Rennie look alike. Coincidence or a clue?
Matt Barr: Callum and I both have hair that sticks straight up. We also have the exact same facial hair, but that's because I thought Callum was such a good actor I wanted to copy him! When all the girls on set had this thing for Callum Keith Rennie, I thought, "Well, I'm going to do what he does!" People stop me on the street saying it's obvious I'm Wakefield's son because I look like him. To be honest, I never thought about that when we were shooting.
TVGuide.com: Why does everyone suck at shooting guns? They cannot fire a shot to literally save their lives, so how are you going to handle two killers?
Barr: [Laughs] OK, here's my theory. Sully does not like guns. He pretty much saved the guns for PlayStation 3 — Call of Duty, some Halo. When you're shooting a real gun, it's a lot different than pushing X on the remote. Other than that, you're right! These are incompetent human beings who don't even deserve to survive. ... Honestly, I got so attached to carrying a gun in Harper's that I want to carry a gun more in shows. I actually went to a gun range the other day and shot guns for real. It felt empowering. I'm not going to lie. Everyone should try it.
TVGuide.com: In the preview, Sully fires a flare of some sort. And they show you, Shea and Madison get a boat, which I'm assuming is not Cal's sailboat.
Barr: Yeah, stuff goes down. We do find a boat and it's not Cal's sailboat. Everyone's kind of compartmentalized, but the gang and Wakefield find themselves together and there's definitely a big showdown between the good guys and the bad guys. There are definitely deaths. Plural. But there's also a group of survivors.
TVGuide.com: Since there are two episodes, will we get a flashback of some sort to see how all the kills were carried out?
Barr: Yes. The audience is going to discover how this master plot went down. It's relatively calculated as to who, what and why, so there is a method to the madness. The payoff is going to be great. People are going to understand how and why and at times, when and why it was relevant.
TVGuide.com: Did you get a back story on Sully, besides him being Henry's best man and close friend? He seemed like a typical frat guy at first, but he's taken a heroic turn and now wants to be "less guarded."
Barr: I think they cut it, but Sully had, like, slept with every girl on the show some time in the past, like in college or in high school or at some family reunion. [Laughs] He definitely made the rounds of the Dunn-Wellington community! In my mind and heart, I had to believe there was more substance to him than being Sully the slut. I thought it was kind of charming that Sully began to realize there's probably a deeper experience that he could have in life after being placed in this extreme circumstance. I love the "less guarded" line. It was the most awkward moment to say it and yet so perfect.
TVGuide.com: This has been bugging me: It seems like Danny and Sully haven't told anyone about Booth's death and Malcolm's involvement. Why haven't they?
Barr: This is a great question. I think it's a bit of selfishness there, like every man for himself. In survival mode, these guys are thinking about the next 60 seconds in front of them as opposed to what happened. Screw the past, although that sounds shallow, doesn't it? ... But I miss Booth. Maybe they can do a prequel. Harper's Island: The College Years. You can see Sully sleep around with everyone.
TVGuide.com: Why is Henry always pairing off with Abby instead of Trish — his fiancée? That's very suspect.
Barr: They do separate a lot, don't they? That's a good point. I thought I knew the show, but apparently not! You've done a lot more homework than I did. But Henry and Abby have known each other for a long time and I think that there's something ingrained in them from their experience that he feels a loyalty to Abby in a way, and a bit of that may be revealed. Maybe that's all I'll say for now!
TVGuide.com: I'd be remiss if I didn't ask: Where's Muffin? She was MIA the last time she was mentioned.
Barr: Thank you! Here's the thing: These guys saw Mr. Wellington get cut in half with a headspade and somehow we have time and effort to go search for Muffin, our blow-up doll, like that's some sort of concern of ours. People give me a hard time about it, but Sully made this connection to this inanimate object and he cares about her. I think he's trying to compensate for the lack of love in his life. In all his sexual endeavors, what he was really looking for is love and I think Muffin did that for him. Man, that sounds weird! [Laughs]
TVGuide.com: Are we going to see her again?
Barr: I don't think so. When the ferry left, there might have been some teenager that found Muffin and stole her and took her to Seattle. I live by the motto "pay it forward." I think Sully can finally let go of Muffin and be less guarded. No more plastic girls, but real girls with beating hearts. Some of the things we see Sully do in the finale shows he's discovered what's important in life and his integrity.
TVGuide.com: What's next for you? Any chance the Gossip Girl spin-off will be picked up midseason?
Barr: There might be a small sliver of a chance, but as far as I know it will just exist as that flashback episode. I just screen-tested for a show, so we'll see. I'm actually producing a movie called Twelve Mighty Orphans. It's a book by Jim Dent about this orphanage and football team in the 1930s and this visionary coach who leads them to a championship. So I'm moonlighting as a producer. I've never produced before. Well, when I was in sixth grade, I produced a school project. So this is the second thing after, like, 3 Ninjas Part 2!
