Continuity mistake: After the police inform Rockford that Prentiss Carr's cause of death was suicide, when it cuts to the closeup of Carr's widow pouring the drink, the woman in the closeup has long nails and is not wearing a belt. In the following shots Janet Carr is wearing a long red belt and her nails are shorter. (00:08:50)
Continuity mistake: In the hotel room, Jim spots the gun under the curtain. The gun is underneath a concave pleat of the curtain in the wide angle, convex in the close-ups. (00:04:25)
Continuity mistake: Escaping the bare-bellied killer in his truck, Rockford drives through an industrial site (lumber yard, turns out). A worker dives out of the way. Then there's a close-up of James Garner vigorously turning the wheel, but in the shot showing the road, the truck actually goes ahead a few meters still, perfectly straight, before the turn occurs. (00:41:40)
Audio problem: Driving his dad's pickup, Rockford gets flanked by one of the worst dressed killers in history. The guy shoots him about 3 times, but the audio is at really low level for a revolver shot from a couple of meters of distance and there's no flash or smoke indicating that any shot in fact is fired. Combined with the fact that it's preposterous that the guy could miss from such a short range and no arm/body movement is present, it's an adequate guess to imagine that the sounds have been added in post to add some sense of danger and were not planned when shooting the actual scene. (00:41:20)
Continuity mistake: When Jim Rockford tells Rockford Sr. that refilling the truck will be 40 gallons, he has his hand at 11 o'clock, and gone out of sight in the next shot. (00:38:00)
Continuity mistake: Rockford intercepts the liquor store delivery for Carr. He then buys himself some time at the front door not to tip off the delivery guy about him not being the actual homeowner. When it cuts to a long shot, the bill note is gone from the paper bag. (00:26:15)
Continuity mistake: Rockford checks out of the receipt from the liquor store. In close-up he folds it neatly and places his thumbs on top. In the medium shot that follows, his thumb is tucked in between two folds. The paper does not look the same either, with a more yellow color. (00:22:35)
Continuity mistake: When the two officers threaten Rockford for putting them in bad light, Police Lt. Earl Furlong has the collar of his shirt perfectly tucked in during the wider shots, but parts of it overlap the right lapel of his jacket in close-ups. (00:16:05)
Continuity mistake: The nasty policemen pull Rockford over. A woman with black hair, a blue jacket and a brown bag is walking from left to right. Later in the scene, when Police Lt. Earl Furlong says Rockford tried to burn them with the Chief, the same woman is walking in the same path and place. (00:16:00)
Visible crew/equipment: Rockford just broke the news to the widow. When he says that none of it makes any sense, in the top right corner of the frame the shadow of the boom mike follows his movement. (00:10:50)
Continuity mistake: When Rockford is checking out of the license plate at the beginning of the episode, the shadow he casts on the trunk and bumper of the car is absent in close-up. (00:02:00)
