Quirky movie great Jack Nicholson is set to shock fans in his new thriller THE DEPARTED by wearing a sex toy in a sleazy scene. The CHINATOWN star, who threatened to set fire to co-star Leonardo Dicaprio to heighten the tension in one scene, felt he'd add to the sick sexual nature of his character FRANK COSTELLO by strapping on a dildo. And, as shocked as co-star Matt Damon was, he admits Nicholson's last-minute decision to wear a sex toy impacted his whole performance in the Martin Scorsese film. Damon says, "It's Sunday night and I'm looking over the script and I'm getting ready and I get a phone call: 'Hello, its Marty... Jack had some ideas for the scene tomorrow in the XXX movie theatre where he meets up with your character and he's gonna wear a dildo.' I said, 'Alright, I'll see you at seven!' "So, we went in the next day and we rehearsed and Jack said, 'Here's the deal - I'm gonna come in and I'm gonna sit there in the overcoat and turn around and I'm gonna pull out the big dildo and we're gonna laugh.' "I thought that was a good idea to get into the scene. Jack brought this incredibly new layer to that character. He made him more obscene in a way that felt authentic. "I said to Marty, 'If Jack is introducing this sexual element into this, then it's fair game in the script and we have to reference it from my character's stand point. "I said, 'We're in this macho world and everyone's beating each other up and knocking each other over the head with glasses and throwing people through walls, and Jack is a sexual dynamo so in contrast I wanted to lose every fight I'm in and I don't want my dick to work. I want to get an aggressive run in the other direction.'"
