Davidarquette_foxtca_240There will be more than one Arquette on NBC this season — just not at the same time.

Actor David Arquette (Scream) will join his sister, Medium star Patricia Arquette, on the Peacock airwaves when he guest-stars on an episode of My Name Is Earl this fall. Alas, NBC will miss out on an opportunity to promote "Arquette Week," as Medium isn’t scheduled to return until after the new year.

In the Earl episode, Arquette will play an amateur stunt man named Sweet Johnny. Earl (Jason Lee) wants to cross Johnny off his list by making up for the fact that he slept with Johnny’s girlfriend a decade earlier — but after he tracks Johnny down, he finds the daredevil in no shape to receive Earl’s goodwill.

My Name Is Earl is the second guest spot Arquette has booked this fall. He’s also set to appear in an episode of ABC’s Pushing Daisies in the early part of the season.

Arquette is currently co-starring in Hamlet 2. His TV credits include ABC’s In Case of Emergency, which aired in the spring of 2007, the miniseries Dead Man’s Walk and guest spots on Friends and Beverly Hills, 90210. He was also an executive producer of Dirt, along with his wife and series star Courteney Cox.

My Name Is Earl begins its fourth season on Thursday, Sept. 25.
