Family Guy's Cleveland courtesy Fox
It looks like Fox just can't get enough of Seth MacFarlane.

According to the Hollywood Reporter, Fox and 20th Century Fox TV are working with MacFarlane to develop a spin-off from his wildly popular series Family Guy. The show would feature Cleveland Brown, Family Guy's mild-mannered voice of caution, in a series tentatively titled Cleveland.

The project is being written by MacFarlane, Mike Henry (who voices Cleveland) and Rich Appel, executive producer of MacFarlane's other Fox series, American Dad. Fox hopes the series will complement their Sunday-night comedy lineup, which features The Simpsons alongside MacFarlane's two other series. - Adam Bryant
