'The Simpsons' New Season Jan. 2014 To Feature Channing Tatum, Seth Rogan, Paul Rudd & Judas Priest Frontman Rob Halford

"The Simpsons" new season will be airing an episode by Judd Apatow, the A-list comedy writer-director-producer.

Several stars will be featured including the voices of Apatow, frequent collaborators Leslie Mann, Paul Rudd, and Seth Rogen, plus Channing Tatum and... Judas Priest frontman Rob Halford.

The episode storyline is based on Homer being fed up with movie theaters. Bart teachers Homer how to illegally download films, and he starts screening them in his backyard for his community 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 executive producer Matt Selman. 

David Arnet plays a FBI director in charge of anti-piracy and focuses on shutting down Homer's operation.

One of the movies that Homer shows is a This is 40-esque Apatow dramedy titled Life is Funny that stars Mann and Rudd. Halford winds up singing a parody of the Judas Priest classic "Breaking The Law" in an effort to nab Homer, while Apatow gives "a hilarious, self-important speech about Hollywood people," says Selman. 

Seth Rogen and Channing Tatum make cameos in the episode as themselves. "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."

The episode titled "Steal This Episode" is scheduled to air in January.
