Leverage

Throughout the third season of TNT's Leverage, Nate (Timothy Hutton) and his team have been on the heels of supervillain Damien Moreau, a ruthless financier of all things criminal. For the December 19 two-part finale, they finally come face-to-face with their nemesis, played by former ER star Goran Visnjic.

"He's the guy who never killed somebody with his own hands, but he's probably responsible for thousands of deaths worldwide," says Visnjic, who initially was hesitant to play a bad guy. But after watching episodes of the crime caper, he quickly changed his mind. "I was like, you know what? This is going to be loads of fun," he tells TV Guide Magazine.

But it was the "go big or go home" approach to acting that turned out to be his biggest challenge. "On the set, Dean [Devlin, executive producer] and Marc [Roskin, director] were telling me, 'Dude, just push it. You can't overdo it.' You have to trust that they're going to use something that is really good, but at the same time, you're allowed to have fun on the set. I actually saw [the episodes] and I'm real happy about them!"
