In order for CHRIS NOTH to reprise his role as the suave Mr. Big in 'Sex and the City -- The Movie,' he had to juggle that with his work on "Law & Order: Criminal Intent," so he ran back and forth from the posh penthouses of Manhattan's Upper East Side to the body bags on the gritty "L&O" locales.

He tells ET's STEVEN COJOCARU, "I had very little sympathy from my crew from 'Law and Order.' I would get back from these marvelous shoots and I would have had the most awesome time with SARAH JESSICA PARKER. I would have the most fun with anybody I've ever worked with, and I love all my partners. I love my partner on 'Law & Order,' but there's just a sense of play with Sarah Jessica. It is what keeps us alive after all these years and fresh. But I would get back to the South Bronx, or wherever we were finding a body, and the crew would be waiting. 'Hey, Mr. Big. Should we get you a Cosmo before finding a body and find out why they blew their head off?'"

And while Chris won't say whether or not Big and Carrie (SARAH JESSICA PARKER) actually get married in the film, he does respond when Cojo calls him both the hero and the devil:

"It's a deep movie actually. There's a lot of great laughs, but there some pretty heavy stuff that I think people are not going to expect. I think it goes to places that the series never went and, I think, that [writer/director MICHAEL PATRICK KING] is exploring us in a much deeper way. I know, for me, it was a pleasure to settle into that. I'm not going to say tragic things that happen, but there's some heartbreaking things that happen. My feeling is if all of us get through what we get through we can get through anything."

"Sex and the City" opens in theaters on May 30.
