Joe Forrester (1975–1976) is an American Crime/Drama TV series, starring Lloyd Bridges as a uniformed foot patrol officer in a run-down neighborhood of Los Angeles. Patricia Crowley co-starred as Georgia Cameron, Joe's romantic interest. Former NYPD Detective Eddie Egan played Sgt. Bernie Vincent, Joe's supervisor. Dwan Smith played Jolene, a resident of the neighborhood Joe patrolled.
Joe Forrester's character was introduced on the TV series Police Story, in a special 90-minute episode "The Return of Joe Forrester", written by Mark Rodgers and directed by Virgil W. Vogel, later retitled Cop on the Beat (1975), and syndicated as a TV-movie. In this pilot, Forrester, a second generation policeman, is a plainclothes officer in LAPD's Metro Division who convinces his superiors to put him back in uniform, and back on a foot beat, in a neighborhood beset by a series of armed robberies which are invariably followed by a vicious rape. When the case is solved, Forrester elects to stay in uniform, and on his foot beat, leading to the subsequent series.
