The real world never never impinges on the entertainment side of television, so fully realized private eyes continued to perform their pulp kabuki all over the tube. Mannix and Cannon and all those fellows, of whom the best was by a long shot Rockford. Rockford didn’t try to break out of the rituals, but used them in a very knowing and able way. His relationships with society, with the police, with his clients, with women, were all very much in the tradition, and yet Rockford was an individual, a human being you could believe in rather than a cardboard figure in a trench coat.

"I grew up on The Rockford Files–I knew nothing back then about who wrote what. I never noticed the names Roy Huggins, Stephen J. Cannell, David Chase, Juanita Bartlett, Meta Rosenberg, until much later. All I knew about James Garner besides this show was that he did those Polaroid commercials with this sarcastic blonde who then showed up on The Rockford Files. Which was confusing. Maybe they should have hired Gretchen Corbett for the commercials, though that might have been even more confusing.
