Neighbors is a 1981 American black comedy film directed by John G. Avildsen and starring John Belushi, Dan Aykroyd, Cathy Moriarty, and Kathryn Walker. Based on the 1980 novel Neighbors by Thomas Berger, the film's plot follows the mild-mannered and conservative Earl Keese (Belushi) as his monotonous suburbanite life is upended by the arrival of his new neighbors, the chaotic and eccentric Victor Zeck (Aykroyd) and his sultry wife Ramona (Moriarty). The film takes liberties with Berger's story and features a more upbeat ending. The screenplay of the film is officially credited to Larry Gelbart, although it was extensively rewritten to Gelbart's public disapproval. Released two and a half months before Belushi's death, Neighbors marks his last film performance.
