The film's cast features a number of British comedians, comic actors, and sitcom stars, most prominently from "Spaced", "Black Books" and "The Office", and co-stars other actors from these same shows. Cast members from them include Pegg, Frost, Stevenson and Peter Serafinowicz. Frost met Pegg when he was working as a waiter, and was brought onto "Spaced" despite a lack of acting experience; Frost explained that Shaun and Ed have a dynamic similar to that of Simon and himself in real life, as they had been living together for years.
