In an interview with TV Week about the upcoming season of “Family Guy,” Seth MacFarlane let drop that “Family Guy: The Movie” will be going into production within a year. “We want to do it. And it is time. In the past six months we have seriously started talking about it,” MacFarlane said. “And my hope is that we will get it going within the next year. Doing the show is a seven-day a week process, so I don’t know how we will squeeze in a movie. But we will figure it out. I have an idea about what it will be. It is definitely something you wouldn’t be able to do on the show. That’s the only reason to do a movie.” When he was asked if there would be nudity and obscenities, MacFarlane added, “Oh, yeah!”

Considering the success of the "Simpsons Movie" this seems like it makes good financial success.
