The search for a new Duffman on Sunday’s The Simpsons (Fox, 8/7c) brings a bevy of familiar voices to Springfield — including one not heard on the show in more than 20 years.
TVLine has an exclusive first look at the episode, offering a behind-the-scenes peek at Cat Deeley (So You Think You Can Dance) and Stacy Keach (Full Circle) getting into character; Deeley plays herself, while Keach once again plays the great H.K. Duff.
Bonus scoop (not in the video): Full Metal Jacket‘s R. Lee Ermey also lends his voice to Sunday’s installment, reprising the role of Colonel Leslie Hapablap, who last appeared in the 1995 episode “Sideshow Bob’s Last Gleaming.”
