Extras

Extras is a British sitcom about extras working in television, film, and theatre. The series was co-produced by the BBC and HBO and was created, written, and directed by Ricky Gervais and Stephen Merchant, both of whom also starred in it. Extras follows the lives of Andy Millman (Gervais), his platonic friend Maggie Jacobs (Ashley Jensen), and Andy's substandard agent and part-time retail employee Darren Lamb (Merchant) as Millman muddles through life as an anonymous "background performer" who eventually finds success as a B-level sitcom star.
