Rex Smith (born September 19, 1955, Jacksonville, Florida) is an American actor and singer. Smith debuted in the Broadway play Grease in 1978. He is noted for his role as Jesse Mach in the 1985 television series Street Hawk, as well as being a singer and stage actor. During the late 1970s, Smith was popular as a teen idol. Because of his good looks, he was featured regularly in 16 Magazine and Tiger Beat. He also had a gold Top 10 single, "You Take My Breath Away," in 1979.
Rex Smith is best known for his role in the short-running 1985 television series Street Hawk: The show itself is about a police officer and former amateur dirt-bike racer named Jesse Mach (Rex Smith) who is secretly chosen to test a top-secret project—an all-terrain attack motorcycle capable of speeds in excess of 300 miles per hour. Backing the motorcycle was a computerized command system that allowed its operator to provide the motorcycle's rider with real-time information from various sources, and even operate the motorcycle on "autopilot" during its high-speed runs, achieved through a process called "hyperthrust".
Norman Tuttle (Joe Regalbuto) was the designer of the motorcycle. An engineer previously employed with the Law Enforcement Assistance Administration of the Department of Justice and subsequently with one of its successor agencies (exactly which one was never specified in the stories) who reported to a certain Mr. Kirby, who never appeared in the stories, Tuttle was initially reluctant to choose Mach to test the motorcycle. But once he had, he was able to convince Mach to commit to the program for life.
Mach began to lead a double life, a police public relations officer by day, and crime-fighter by night. Street Hawk (actually "The Street Hawk") was regarded as a lawless vigilante, and hence a fugitive from justice, by the police.
