It's been talked about for quite a while now but Seth MacFarlane made it official to Wired. A Family Guy movie is in the works.
“Fox wants it. We know what we want to do with it. It’s just a question of finding the time,” he said. “That’s why The Simpsons took so many years to do theirs. It wasn’t because they didn’t know what they wanted to do with it. They just couldn’t fit it into the schedule.
“There’s so much to do for a weekly animated series — twice as much as you have to do for a live-action show. So, we’re finding time where we can. We’re in the early stages right now.”
If it's half as good as Family Guy: Blue Harvest, their spoof on Star Wars, it'll be hilarious.
