Sharky's Machine is a 1981 motion picture directed by Burt Reynolds, who stars in the title role. The movie is an adaptation of William Diehl's first novel Sharky's Machine (1978), with a screenplay by Gerald Di Pego. Its cast included Burt Reynolds, Vittorio Gassman, Brian Keith, Charles Durning, Earl Holliman, Rachel Ward, Bernie Casey, Henry Silva, and Richard Libertini. Tom Sharky (Burt Reynolds) is a narcotics police Sergeant in Atlanta who is working on a transaction with a drug dealer. Another member of the force, Smiley (Darryl Hickman), shows up unexpectedly during the sting, causing the drug dealer to run and Sharky to give chase, ultimately shooting the suspect on a MARTA bus only after the wounding of the bus driver. In the aftermath, Sharky is demoted to vice-squad, which is considered the least desirable assignment in the police department.
