The actor caused controversy in April after claiming that the NBC show will wrap up its run next year.
30 Rock creator and star Tina Fey was quick to deny that she plans to end the sitcom and Baldwin eventually clarified his remarks by saying that he hopes the show "goes on forever".
In a new interview with The AP, Baldwin disclosed that he is seriously considering leaving 30 Rock even if it continues past its sixth season.
"That's pretty much all I think about right now," the star said. "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."
He continued: "It's been a great experience, and I've loved doing the show. 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."
Even if he does decide to leave the NBC sitcom, Baldwin expressed doubt as to whether he'll return to film work on a full-time basis.
"When I go back into the world to go to work, I don't know how likely I would be to [make movies]. This is something I can't answer now… I look at romantic comedies and independent films, quirky comedies, and I think I don't really appreciate them that much," he explained.
"All of this is as a result of doing 30 Rock, because I've really been completely tainted by the people I work with because they're so funny... It's tough to find something that's really, really well written."
This week, it was reported that Baldwin has rejoined the cast of Rock of Ages after previously pulling out of the project for unspecified reasons.
