VIDEO: Fishburne Previews the Reveal of His CSI's Dark Side

"There's going to be an episode where you get to see this 'aggressive tendency,'" Fishburne shares in the video Q&A below. OK, but just how unsettling can this new side of Langston be? Says Fishburne with a chuckle, "With CSI, you can never worry about being too dark.... I'm anxious to see where it goes."
