The list of impressive and eclectic guest voices continues to grow, with actors like Kiefer Sutherland, Natalie Portman, Michael Imperioli, Joe Pantoliano, Joe Mantegna, The White Stripes and Dr. Phil McGraw making voice appearances next season on THE SIMPSONS airing Sundays (8:00-8:30 PM ET/PT) on FOX.

Homer becomes a made man in the 18th season premiere episode "The Mook, The Chef, The Wife And His Homer," airing Sunday, Sept. 10 (8:00-8:30 PM ET/PT). After Lisa befriends Fat Tony's (Mantegna, reprising his role as Springfield's infamous mob boss) son Michael, Fat Tony invites the Simpsons over for dinner as a sign of gratitude. Shockingly, Fat Tony is shot by a rival family moments after Michael admits he would rather be a chef than take over the family business. Fat Tony's main thugs, Dante and Dante Jr. (guest voices Pantoliano and Imperioli), want Michael to be the new kingpin, but when he declines, Homer steps up and leads the family on a major mob spree.

The White Stripes guest-star as themselves in "Jazzy And The Pussycats" Sunday, Sept. 17. After Bart's arm is mangled by a tiger that Lisa rescued from the local pound, Bart organizes a benefit concert to raise money for an operation to repair his drumming arm.

Dr. Phil McGraw, Fran Drescher and comedian Richard Lewis stir up tricks and treats in the annual "ghoultide" Halloween trilogy, "Treehouse of Horror XVII," Sunday, Nov. 5.

In "GI (Annoyed Grunt)," Sunday, Nov. 12, after Bart gets out of a commitment to join the Army at 18, Homer falls prey to a couple of Army recruiters and lands himself in basic training. Homer, of course, treats this like summer camp and infuriates his hard-nosed colonel (Sutherland) when he is unfazed by the constant hazing and humiliation.

Other upcoming guest voices include famed authors Tom Wolfe, Gore Vidal, Michael Chabon and Jonathan Franzen. Later in the season, Portman, Lovitz, White, Hamlin and Idle also pay Springfield a visit.
