Tina Fey's role in "Admission" marks a departure from her portrayal of Liz Lemon on "30 Rock" -- she says "f--k" during one of the film's more dramatic moments -- but Fey says she drew the line at appearing naked onscreen.

"The first meeting I had with [director] Paul Weitz and [screenwriter] Karen Croner, we talked a little about the feminist politics of movie, and also, originally, the movie was closer to the book in that it had a couple of legitimate sex scenes in it," Fey told Movieline in a new interview (watch above). "I was like, 'Er,'" the actress said before pantomiming a sign for cutting. "They were kind enough to accomodate that."

In the new film, Fey stars as a college admissions counselor who has her life turned upside when an old acquaintance (played by Paul Rudd) comes back into her life. "Admission" is based on the novel by Jean Hanff Korelitz.

"For me, the part of what would determine if I could even do a movie was that when we were doing '30 Rock,' I would only have a little window of time in the late spring, early summer to shoot anything," Fey told HuffPost Entertainment about "Admission" and its post-"30 Rock" timing. "In the middle of the summer, we'd go back to writing '30 Rock' and start shooting in the fall -- and that's like nine months of the year. So mostly it's just luck that it came together at all."
