Police Story is an anthology television crime drama that aired on NBC from 1973 through 1978. The show was the brainchild of author and former policeman Joseph Wambaugh and represented a major step forward in the realistic depiction of police work and violence on network TV. It was produced by David Gerber and Mel Swope.
Although it was an anthology, there were certain things that all episodes had in common; for instance, the main character in each episode was a police officer. The setting was always Los Angeles and the characters always worked for some branch of the LAPD. Also, notwithstanding the anthology format, there were recurring characters. Scott Brady appeared in more than a dozen episodes as ‘Vinnie’, a former cop who, upon retirement, had opened a bar catering to police officers, and who acted as a sort of Greek chorus during the run of the series, commenting on the characters and plots. Tony Lo Bianco and Don Meredith made several appearances as Robbery-Homicide Division partners Tony Calabrese and Bert Jameson. Other recurring characters included surveillance specialist Joe LaFrieda, played by Vic Morrow, and vice officer turned homicide detective Charlie Czonka, played by James Farentino.
Police Story was a precursor to later shows such as Hill Street Blues, ABC’s NYPD Blue and NBC’s own Homicide: Life on the Street in 1993. Numerous actors, sports figures and former real cops who were familiar to audiences in the 1960′s and 70′s made appearances on the series, including Ed Asner, David Janssen, John Saxon, Robert Forster, Jan-Michael Vincent, Sylvester Stallone, Michael Cole and Eddie Egan.
Sylvester Stallone starred as Caddo in the Season Three episode ‘The Cutting Edge’ (1975).
