In the series storyline, James Scott "Jim" Rockford had served time in California's San Quentin Prison in the 1960s due to a wrongful conviction. After five years, he was pardoned (not paroled, a distinction frequently mentioned in plot points). His jobs as a private investigator barely allow him to maintain his weathered mobile home (which doubles as his office) in a parking lot on a beach in Malibu, California.
In early episodes of the first season, Rockford's trailer is located in a parking lot alongside the highway at 22878 Pacific Coast Highway, Malibu, and near the ocean; for the rest of the series, the trailer is at Paradise Cove (address 29 Cove Road), adjacent to a pier and a restaurant ("The Sand Castle", now known as the "Paradise Cove Beach Cafe").
In contrast to sharp-dressed, pugnacious television private eyes of the time, Rockford wears casual, off-the-rack clothing and tries to avoid physical altercations. He can hold his own in a one-on-one fistfight, but is frequently overpowered when ambushed or outnumbered, often from behind. But he almost always winds up figuring out what's going on, catching the bad guys/gals, and usually exacting revenge by the end of the episode, with some notable exceptions. He is experienced, observant, tenacious, quick-thinking, and has a faculty for impersonation and accents (usually Southern, drawing on Garner's Oklahoma background).
He rarely carries his Colt Detective Special revolver, for which he has no permit and usually stores in a cookie jar; and prefers to talk his way out of trouble. He works on cold cases, missing persons investigations, and low-budget insurance scams, repeatedly stating that he does not handle "open cases" to avoid trouble with the police. (This self-imposed rule was relaxed in later seasons, after "trouble with the police" became a frequent plot device.)
Rockford has been a private investigator since 1968 (according to his Yellow Pages ad, glimpsed in a few episodes), and his oft-quoted fee, when he can collect it, is $200 per day plus expenses[3][4] ($200 at the series' beginning in September 1974 was the inflation-adjusted equivalent of $1,200 in 2023).[5] By the time of the 1990s reunion movies, Rockford's fee was $450 a day, plus expenses. Rockford is very insistent on his fee, but in a running gag, circumstances often conspire to prevent Rockford from collecting the full amount he's owed after a case.
Dennis Becker: Rockford's pursuit of cases often leads to difficulties with his friend in the LAPD, Sgt. Dennis Becker (Joe Santos), a homicide detective struggling to advance in the department under a series of overbearing lieutenants. The two most notable are Alex/Thomas Diehl (Tom Atkins) during the first, second and fourth seasons and Doug Chapman (James Luisi) in the third to sixth seasons. Those higher-ups invariably dislike Rockford (and private investigators generally) because of their perception that either he is meddling in open cases or is trying to make the LAPD look incompetent in its handling of closed cases. Further, Rockford often calls Becker asking for favors, such as running license plates through the California Department of Motor Vehicles (DMV) computer system, often annoying the already overworked cop. By the fifth season, Becker is promoted to lieutenant; it was stated in the episode where Becker is promoted that Becker's association with Rockford, considered by LAPD brass to be a shifty ex-con, had hampered Becker's chances for promotion.[6] Chapman was irritated when Becker became his "equal". In season 6 episode The Big Cheese, the third-to-last of the series, Rockford gets a degree of revenge when Chapman inadvertently makes incriminating statements about his tax evasion before an undercover IRS agent who is with Rockford. Becker appears in 89 of the 123 episodes.
Joseph "Rocky" Rockford: Rockford's father, Joseph "Rocky" Rockford, is an ex-Seabee, semi-retired, semi-truck driver who nags his son to find stable (and less dangerous) employment, often urging him to follow in his footsteps as a truck driver (especially in early seasons), and often wishing Jim would get married. The relationship of father and son was an integral part of the show. Rocky appears in 101 episodes, and usually becomes involved (like it or not) in his son's cases. Occasionally, he hires Jim himself. Jim Rockford's mother is never shown or named, and is very seldom referred to; it's implied, but never stated directly, that she died some years ago.
Beth Davenport: Rockford has a close relationship with his attorney, the idealistic, tenacious Elizabeth "Beth" Davenport (Gretchen Corbett). In second-season episode "A Portrait of Elizabeth", it is explained that Beth and Rockford had dated for a time (prior to the beginning of the series), but she soon became aware of his emotional unavailability and lack of interest in a long-term relationship, and realized that they would be better off as friends (although the two do seem to still casually date on occasion during early seasons).
Angel Martin: Rockford's scheming former San Quentin cellmate, Evelyn "Angel" Martin was something of a comic relief character played by Stuart Margolin. Jim employs Angel as an operative from time to time, often to gather street-level information, or to help him access the files of the newspaper where Angel works as a low-level filing clerk. Keeping this job is a condition of Angel's parole; even so, it is doubtful that the ever-shifty Angel would be capable of doing so, except that his brother-in-law owns the paper. Jim also uses Angel on a few occasions to play a supporting role in con games that he sets up to sting especially difficult adversaries.
Others:After Corbett was dropped from the show following the fourth season (allegedly due to contract disputes between Universal, which owned her contract, and Cherokee Productions, Garner's company), John Cooper (Bo Hopkins), a disbarred attorney, was added as a new adviser for the frequent legal problems in which Rockford would become entangled. A new romantic interest, Dr. Megan Dougherty (Kathryn Harrold), a blind but highly independent psychiatrist, appears in two episodes in seasons five and six ("Black Mirror" and "Love Is the Word", respectively) and the 1996 television movie The Rockford Files: Punishment and Crime.[7]
The show's pilot was written by Cannell, who also wrote 36 episodes and was the show's co-creator. Juanita Bartlett, one of the show's producers and Garner's partner at Cherokee Productions, wrote 34 episodes. She also wrote for Scarecrow and Mrs. King, The Greatest American Hero, and In the Heat of the Night. David Chase wrote 16 episodes; he later went on to Northern Exposure and The Sopranos. The show's co-creator, Roy Huggins, also wrote for the show during the first season, always using pen name John Thomas James. However, Huggins' contributions to the show ended midway through the first season, after he submitted a script rewrite direct to set as the episode was shooting, without getting approval from any other writer or producer. Garner, trying to work with the material on set, felt the rewrite was unsatisfactory, and could not figure out why it had been approved for shooting. When he discovered that neither Cannell nor any of the other production staff members knew anything about the rewrite, Garner issued a directive that Cannell, not Huggins, had final say on all script material. Though Huggins was credited as a producer for the entire run of the series, this effectively ended his creative involvement with the show, as he submitted no further material to The Rockford Files and did not involve himself in the day-to-day running of the series.
Frequent directors included William Wiard (23 episodes), Lawrence Doheny (10 episodes), and Ivan Dixon (previously a regular on Hogan's Heroes) (nine episodes). Veteran actor James Coburn directed an episode. Coburn had co-starred with Garner in the classic movies The Great Escape (1963) and The Americanization of Emily (1964). Other actors who directed episodes include Jackie Cooper (three episodes), as well as Richard Crenna and Dana Elcar (one episode each). Co-creator Stephen J. Cannell directed several episodes; executive producer Meta Rosenberg directed six episodes; series regular Stuart Margolin helmed two; and James Garner directed one episode in the second season, "The Girl in The Bay City Boys' Club". It was Garner's only directing credit in his entire fifty-plus-year film career; in his autobiography, The Garner Files, Garner states he only took on the assignment because the scheduled director was unexpectedly unavailable at the last minute.
Familiar to viewers was Jim Rockford's gold Pontiac Firebird Esprit car. One oft-recurring element of the show was the famous "Jim Rockford turn-around" (also known as a J-turn or a "moonshiner's turn" - commonly employed as an evasive driving technique taught to Secret Service).[8][9] Garner explained the move in his 2011 autobiography The Garner Files: "When you are going straight in reverse about 35 miles an hour, you come off the gas pedal, go hard left, and pull on the emergency brake. That locks the wheels and throws the front end around. Then you release everything, hit the gas, and off you go in the opposite direction." Garner stated in a Season One DVD interview that he performed this stunt for the duration of the series. The car's license plate was 853 OKG, although the plate in some early episodes displayed the number 835 OKG. Garner writes in his autobiography that he believes that the letters OKG stood for "Oklahoma Garner" but that he does not know the origin of the number 853.
Starting with the 1974 model year, Rockford would get a new model-year Pontiac Firebird each year throughout the series. The Firebirds used had an identical "copper mist" color with the Esprit's exterior and interior. Although the Firebirds were badged as Esprits, they were actually the higher performance "Formula" model without the twin scoop hood. Garner needed Rockford's car to look like the lower tiered "Esprit" model, a car Rockford could afford, but have the performance necessary for the chase sequences in the show. To achieve this, the show featured Pontiac Firebird Formulas re-badged and re-hooded to look like the "Esprit" model. The "Formula" model was developed to provide the performance of the top-level "Trans Am" in a less ostentatious form. Formulas didn't have the Shaker hood scoop, side vents, graphics or lettering used on the Trans Am, but they had the same higher horsepower engines and drive trains, larger front and rear anti-sway bars, stiffer springs and shocks, and a twin scoop hood. (Sharp-eyed car connoisseurs can spot the twin exhausts and rear anti-sway bar on the cars used on the show, options that were not part of the "Esprit" package, as well as spot the different model year cars used in various chase scenes that differed from those in an actual episode, especially in later seasons.) Although the series ran until early 1980, no Firebird was used past the 1978 model year as Garner reportedly was displeased with the restyled front end of the 1979 and later Firebird models and as such did not wish them featured on the show (although an answering machine message in one episode in the final season indicated his car was a 1979 Firebird).
