Alec Baldwin says "30 Rock" changed his life and has not decided what he will do when he leaves.
The 53-year-old actor has played Jack Donaghy on the NBC comedy series since it debuted in 2006 and has one season left on his contract with NBC. Baldwin, who has not ruled out a political career, has said he will leave at that point.
"That's pretty much all I think about right now," Baldwin told the Associated Press. "To finish the show, I'm going to do this year then start thinking about what I want to do next. It's the big question."
"It's been a great experience, and I've loved doing the show," he added. "It changed my life. I'll never have it this good again, I know that. But I know that I've got to do something different, try something different. I don't know what that's going to be."
Baldwin told CNN's Eliot Spitzer several months ago that he was interested in politics but said that to quit acting would be "enormously difficult."
"It would be easier for me to run if I moved - California or Connecticut or somewhere," Baldwin, a New York resident, told the Associated Press. "And I'm not prepared to do that right now."
Baldwin has meanwhile been keeping busy with his movie career. He stars in the upcoming film adaptation of the Broadway hit "Rock of Ages." Despite a recent report that said he had left the project, Baldwin is still a part of the production.
In recent days, director Adam Shankman has been talking about his experiences making the movie with Baldwin and several other actors on his Twitter page.
"@rustyrockets and alec Baldwin were so good , we added a mash up for them," Shankman Tweeted on Tuesday, May 17. "Add @Diegoboneta & @juliannehough, & amp; it's epic."
The film will be based on the hit Broadway musical which features 1980s "hair metal" hits from bands like Journey, Bon Jovi, and Twisted Sister. Baldwin, who has appeared in films such as "Beetlejuice" and "It's Complicated," portrays Dennis Dupree, an ex-rocker who runs a club in Los Angeles' famed Sunset Strip rock district.
Russell Brand (Twitter user rustyrockets), plays Lonny and Diego Boneta portrays Drew. The movie also stars Tom Cruise, Catherine Zeta-Jones, Bryan Cranston and Malin Ackerman.
Cruise's character, rocker Stacee Jaxx, is expected to sing Bon Jovi's "Wanted Dead or Alive." His character is also a part of other several other musical numbers . The Broadway musical starred "American Idol" alum Constantine Maroulis."Dancing With the Stars" professional Julianne Hough portrays Sherrie, a small-town girl who catches the eye of Cruise's character. Hough may also be seen in some provocative outfits since her character becomes a stripper.
Catherine Zeta-Jones is playing an "arch-conservative" villain and Paul Giamatti had signed on to play the manager of the rock band headed by Jaxx.
Shankman, who also directed the musical film re-make of "Hairspray," previously announced on his Twitter that "Rock of Ages" would be released on June 1, 2012 and that filming will start in May.
