Murphy's Law is a 1986 American neo-noir[2] action thriller film directed by J. Lee Thompson from a screenplay by Gail Morgan Hickman.

The film stars Charles Bronson and Kathleen Wilhoite in lead roles with a supporting cast that includes Carrie Snodgress, Robert F. Lyons, and Richard Romanus.

The film marks the sixth collaboration between Bronson and director J. Lee Thompson (following 1976's St. Ives, 1977's The White Buffalo, 1980's Caboblanco, 1983's 10 to Midnight, and 1984's The Evil That Men Do).

Jack Murphy (Bronson), a hardened, antisocial alcoholic LAPD detective, frequently escapes the harsh reality that his ex-wife (Angel Tompkins) has become a stripper and his career is going nowhere by drinking.

Murphy calls for reinforcements and is met with skepticism, unaware that the detective he notified, Ed Reineke, is a mole working for mob boss Vincenzo.

Variety gave a mixed review of Murphy's Law, referring to the film as a "very violent urban crime meller, is tiresome but too filled with extreme incident to be boring.
