As previously reported, former ER star Goran Visnjic has signed on for a key Leverage role.

The actor will take on the key, villainous character of Damien Moreau, appearing in back-to-back December episodes of this TNT drama. Below, we've posted a photo of Visnjic and Timothy Hutton's Nate from the December 19 installment:

"He's the guy who never killed somebody with his own hands, but he's probably responsible for thousands of deaths worldwide," Visnjic told TV Guide Magazine of the character, adding: I actually saw [the episodes] and I'm real happy about them!"

We're excited to see Visnjic in a role so different than the one he played for nine years on ER. Remember: when Leverage returns with new episodes, TV Fanatic will cover each one in-depth, recap and review style!
