Scream 3 (2000)
Patrick Dempsey: Mark Kincaid
Sidney : What do you know about trilogies?
Mark : You mean like movie trilogies?
Sidney : You seem to like movies, Detective.
Mark : Call me "Mark", will you? 'Cause I'm gonna keep calling you Sidney.
Sidney : I'll call you "Mark" when you catch the killer, Detective.
Mark : Well, all I know about trilogies is that in the third one, all bets are off.
Sidney : Did you request this case?
Mark : No. They tend to put me on the ones that deal with the business. I grew up here and I know my way around the studios.
Sidney : Must be exciting. Beautiful place, beautiful people.
Mark : To me, Hollywood is about death.
Sidney : Excuse me?
Mark : I'm a homicide cop. When you see what I see day in and day out, the violence that people do to each other, you get haunted. I think you know about that.
Sidney : What do you mean?
Mark : I know what it's like to see ghosts that don't go away, to be watching a scary movie in your head, whether you want to or not, watching it alone.
Sidney : Ghosts are tough. You can't shoot ghosts.
Mark : Can't arrest ghosts. But the trick to keep from getting haunted is to be with people. You're here, you're not in hiding. You've done the right thing... Miss Prescott.
Mark : What did you know about your Mother?
Sidney : I always thought I had the perfect Mom, the perfect family until I found out I was wrong. She had a secret life and I tried to understand that. And... soon as I thought... then I had more secrets. I don't know who my Mom was.
Mark : You knew who she was to you.
[They stare at each other, quietly, for a few seconds, then he gets up, putting on his jacket, getting ready to leave]
Mark : Here's the deal: I'm off to search the set. I think that what you saw is real. That's the good news.
Sidney : How's that good news?
Mark : Because it means that we are dealing with a flesh and blood killer, and I know how to handle guys like that.
Sidney : Oh, yeah. How?
Mark : Catch him or kill him.
[He begins walking out of his office]
Sidney : Hey, Detective?
[Turning around to face him]
Sidney : What's your favorite scary movie?
Mark : [Walking back over to her] My life.
[He walks away]
Sidney : [to herself, after Kincaid leaves] Mine, too.
