"This episode really keeps Goren and Eames on their toes," Erbe says of the Season 10 premiere. "We would think we were on one path — we had someone in our sights who we thought was guilty — and then they would be killed."
The first case of the series' final season involves a murdered young call girl and the hard-partying, train-wreck fashion designer behind her. The episode, inspired by Charlie Sheen's recent troubles, features Jay Mohr in the Sheen role.
"We had an amazing time," Erbe says. "Jay literally had the crew on the floor laughing in every scene he was in."
