Entertainment Weekly has reported that Judas Priest frontman Rob Halford will lend his voice to an upcoming ‘The Simpsons’ episode that will air sometime next year. The episode will star Will Arnett, director Judd Apatow, and his frequent costars Leslie Mann, Paul Rudd and Seth Rogen.

Simpsons executive producer Matt Selman says that in the episode, titled “Steal This Episode”, Homer is taught by Bart how to illegally download films, and he starts screening them in his backyard for folks in Springfield. “Even though Homer is stealing, he’s doing it for the community, he’s doing it out of the goodness of his heart,” says Selman. One of the movies that Homer shows is a This is 40-esque Apatow dramedy titled ‘Life is Funny’ that stars Mann and Rudd, who joined forces in Knocked Up and This is 40. The FBI goes after Homer, with Halford singing a parody of the Judas Priest classic ‘Breaking The Law’ to help the effort.

Apatow testifies against our patriarch “with a hilarious, self-important speech about Hollywood people,” says Selman. Another Knocked Up star, Rogen, has a cameo role as himself, as does Channing Tatum. “Channing Tatum loves to do surprise twists in movies, a la This is the End,” hints Selman, “and he has a surprise twist in this one too.”
