Number One with a Bullet is a 1987 American action comedy film directed by Jack Smight and starring Robert Carradine, Billy Dee Williams, Valerie Bertinelli, Peter Graves, Doris Roberts, Bobby Di Cicco, Ray Girardin, Barry Sattels, Mykelti Williamson, Alex Rebar and Jon Gries.

Nick Barzack ("Berserk"), an irrational, unkempt and unpredictable cop, and Frank Hazeltine, his cultured, polite, and suave partner, follow a circuitous and highly circumstantial trail of clues, evidence, witnesses, and accomplices through Los Angeles.

The ladies' man Hazeltine and the borderline psychotic Berzack are narcotics detectives with a long history of wild behavior and effective work.

Director Jack Smight said he wanted to cast Denzel Washington as Hazeltine but Cannon executive Menahem Golan was not interested and sought someone with more star power.

[3] The Barzack character was originally assigned to co-writer Jim Belushi but he left the film in its pre-production stage late in 1985 citing creative differences.

Shooting of the film took place in Los Angeles in March 1986 shortly after Carradine signed on and ended in late October of that year.
