From the moment ex-con turned private detective Jim Rockford's phone rings in the opening sequence, you can expect a mixture of action and mystery with a few laughs thrown in.
Jim Rockford broke the stereotype of the private detective. An ex-con, he shied away from guns and violence and prefered fishing to chasing down bad guys.
Instead of a sexy secretary, Jim had his dad Rocky (wonderfully played by Noah Beery Jr.), his ex-cellmate Angel (Stuart Margolin), his lawyer Beth (Gretchen Corbett) and Det. Dennis Becker (Joe Santos) pulling him in assorted directions. Rocky never approved of his son's choice of career. Angel usually tried to drag Jim into some scheme or other while claiming to be helping Jim investigate a case. Beth tried to be the voice of reason, but rarely won out. Becker usually did his best to stay out of trouble for helping or simply knowing Jim Rockford. Like Beth, he rarely succeeded.
Instead of an office, Jim worked out of his broken down mobile home which was close enough to the beach for Jim to go fishing instead of working.
Instead of being the invincible hero, Jim regularly got beaten up by assorted villains and bad guys.
Despite all of that, Jim Rockford managed to solve the case, get the people responsible and set things right by the end of the episode.
I always enjoyed the opening sequence of this show. Although the greeting on Jim Rockford's answering machine never changed, the message left for him was always different and rarely had anything to do with the episode that followed.
