Stupendous DVD sales of Family Guy not only brought the once-canceled show back on the air but also led to the release of a feature-length, direct-to-video movie, Family Guy Presents: Stewie Griffin - The Untold Story, according to The Hollywood Reporter. Now, creator Seth MacFarlane is hoping the DVD debut of American Dad, his latest series, also will lead to a direct-to-video feature.

"It's already been talked about very seriously", he said. "The only reason it hasn't gotten under way yet is time, building time into the schedule that doesn't distract from the show." The Family Guy movie was made at a time when the show was just returning to the air after a two-year-hiatus, MacFarlane said. "We had two years' worth of story energy stored up," he said, "and we were able to come up with something that's worthy of a longer form."
