Seth MacFarlane: 'Family Guy' Movie Coming, Show Maybe Should Have Ended

He's already larger than life, and now Peter Griffin is headed to the big screen.

Seth MacFarlane, creator of the hit series "Family Guy" and the empire it spawned, tells The Hollywood Reporter that there is a deal in place to create a film featuring Griffin family and the rest of the zany world of Quahog. In fact, he envisions a new film every few years, instead of continuing on with the television series.

"Part of me thinks that 'Family Guy' should have already ended. I think seven seasons is about the right lifespan for a TV series," he said -- the show is now on its seventh season, after having been canceled in 2001 and brought back in 2004. "I talk to the fans and in a way I'm kind of secretly hoping for them to say we're done with it. There are plenty of people who say the show is kind of over the hill… but still the vast majority go pale in the face when I mention the possibility."

The film, THR says, is currently being written, with a deal already in place. They've already put out a number of direct-to-DVD films, including, "Family Guy Presents Stewie Griffin: The Untold Story" and "Family Guy Presents: It's a Trap!"

MacFarlane has a number of other animated series, including the spinoff "The Cleveland Show," the military spoof "American Dad," and the upcoming remake of "The Flintstones." He's also expanding into live action movies, the Mark Wahlberg and Mila Kunis-starring "Ted," about a man who believes a giant stuffed animal is controlling his life.
