Charlie calls Jim "Bunkie" as they shared a cell together in San Quentin.
We find out in this episode that Jim spent five years in San Quentin prison and that his cell mate was Charlie Harris.
Goof: In the opening scene, the car being driven by Stone and Willet loses a hubcap when rounding a curve. But when they arrive at Claire's apartment building it's back on the wheel. In a later scene the hubcap is once again missing.
First appearance of Angel Martin.
Jim manages to track down Dick Shaefer by the registration number of his car; 811 QJK.
Senator Murdock drives a maroon red 1973 Buick Riviera, license plate
The original name of the company in this episode was "Financial Dynamics." For some reason this was changed to "Fiscal Dynamics" so every time someone mentions the full name of the company the line of dialog is dubbed over.
When Jim calls the police station, he asks for Lt. Becker instead of Sgt. Becker.
Trivia: In the opening scene, Rockford, dressed incognito, is sitting in the back of a bus hiding behind the sports page of a newspaper. The headline reads "Angels Lose 11th Straight." In the summer of 1974 the California Angels lost their 11th game in a row on July 10, making the date of the paper Rockford is reading Thursday July 11, 1974.
At the beginning of the episode, the camera pans over Monaco; when we zoom in to see where Jim is, all the cars have Swiss number plates, Lausanne to be precise.
When they show the train at night, the footage is shown reversed, as can be seen by the lit "57" number board on the front of the engine being backwards. A few minutes later, when they show the side of the train, the numbers on the side are also backward.
When Jim returns home from the police station, he parks between the lines in the parking space by his trailer. When he comes back out to his car a minute or so later, his car is straddling the line.
At the end of the show, Rockford is forced into a car at gunpoint. The car is a black Mercury with the hidden headlights similar to the type McGarrett always drove on Hawaii Five-O. When the car goes over the cliff and Rockford bails out, the car is suddenly an old Lincoln with the suicide doors and of course the headlights are showing.
This episode marks the first appearance of Gretchen Corbett as Beth Davenport.
Nitpick: As fun as the bathroom scene where Jim puts handwash soap over the floor to cause the thug to slip over, the soap seems far too runny to be regular soap, and it's unlikely that the small amount of soap (or whatever it was) would cause the thug to completely slip over. Great scene though!
Jim's 1/4 page advertisement in the Yellow Pages has no telephone number shown!!! This must explain why most clients came to the door as opposed to calling.
The Pilot is simply called 'The Rockford Files', but it also airs in a two part format called 'Backlash of the Hunter - separate shows with additional filler scenes to bring the viewing time up to fifty minutes.
Three scenes were reused within the the two part version of the pilot, the most glaring being character Jerry Grimes shown in the Mayfair lounge with a poster of Rose Marie in the background, only to be shown later in the episode in a nightclub called Gazzarri's sitting at the same stool with the same poster in the background.
