With all of the CSI-style forensic cop shows on TV, it may be hard to remember that network television was once ruled by cowboys and two-fisted private eyes.
One of the first of the shamuses was Richard Diamond, Private Detective.
The show was one of the first on TV because it had been a long-running, successful radio series. The radio show was created by Blake Edwards, who was later to create TV detective Peter Gunn as well as the bumbling Inspector Clouseau of Pink Panther film fame.
Diamond had been played on radio by Dick Powell, but when it made the jump to CBS television, Powell stepped behind the camera as Executive Producer. In his place a young David Janssen was cast, beginning what was a very long career as a television star (The Fugitive, O’Hara, U.S. Treasury, Harry O, etc.).
