K-9 is a 1989 American buddy cop action comedy film starring Jim Belushi and Mel Harris. It was directed by Rod Daniel, written by Steven Siegel and Scott Myers, produced by Lawrence Gordon and Charles Gordon, and released by Universal Pictures. Belushi plays bad-tempered San Diego police detective Michael Dooley, who has been tagged for execution by a major international drug dealer named Ken Lyman (played by Kevin Tighe). To help, K-9 Sergeant Brannigan (played by Ed O'Neill) gives Dooley an unorthodox drug-sniffing police dog called "Jerry Lee" (named after rock-and-roll singer Jerry Lee Lewis).
