This fall, FOX's animated centerpiece "The Simpsons" will enter its 15th season with a diverse slate of vocal talent including several returning celebrity favorites.

In the season's premiere episode, "My Mother the Carjacker," Glenn Close will return as Homer's fugitive mother who returns to Springfield only to get sent to jail. Later in the season, Jackie Mason reenters the cartoon fold as Rabbi Krustofsky, father of television's Krusty the Clown.

The 14th installment of the series' "Treehouse of Horrors" series will feature "Alias" star Jennifer Garner and boxer Oscar De La Hoya playing themselves themselves and Jerry Lewis will also make a cameo as, fittingly, the father of the show's nutty Professor Frink.

As has already been reported, the Simpsons will go to England in the episode "The Regina Monologues." Prime Minister Tony Blair, J.K. Rowling, Ian McKellan and Evan Marriott will voice yellow versions of themselves. Jane Leeves also adds her pipes to the episode as Grandpa Simpson's old flame.

Oscar-winning filmmaker Michael Moore, Simon Cowell, Mr. T and the late Robert Stack will also be featured during the season.
