Backlash of the Hunter - S1-E1
Continuity mistake: When Dr. Ruben Seelman stands to add 'just one more thing' before Jim leaves, he's holding a pen and a bone in hand, but just the pen remains in the following shot. (00:29:50)
Backlash of the Hunter - S1-E1
Continuity mistake: At the odd restaurant where Rockford puts on the rather flashy tie, continuity is spotty when the two sit down to have dinner. The position of the menu and Sara's arm are obviously changing with the reverse shots. (00:26:15)
Backlash of the Hunter - S1-E1
Continuity mistake: Sara tells Rockford that the mysterious woman is, according to her brother, very attractive. Rockford has in hand the same glass her just put down as he made the joke about her being dredged from the river. (00:19:30)
Backlash of the Hunter - S1-E1
Continuity mistake: After meeting the brother of his client, Jim Rockford sits at the table with her. The cup has its handle pointed towards her hand, away from the hand in the reverse shot. (00:18:10)
Backlash of the Hunter - S1-E1
Continuity mistake: Rockford's client sits down and signs the bank check without any fuss. During the whole conversation that happens and follows, Sara Butler is casting a shadow on the grill behind her in the wide angles, on the wall by it in the close-ups. (00:14:00)
The Countess - S1-E4
Continuity mistake: The bow tie cop cuffs Rockford up; his boot is closer to Jim's shoulder in close-ups. (00:20:45)
Backlash of the Hunter - S1-E1
Continuity mistake: Rockford checks out of the client's cheque with both hands in the wide shot, just one in the close-up. (00:14:15)
Backlash of the Hunter - S1-E1
Continuity mistake: In the phone call at the beginning of the episode, once Jerry answers it cuts to Mildred, and then back to Jimmy, but in a mirrored shot. He's to the other side of the door and holds the receiver in the other hand. (00:03:11)
Continuity mistake: Very early in the episode Aura Lee is hitchhiking while carrying a large suitcase. She runs to the car driven by Robert Webber and stands outside the car with the suitcase in hand, which disappears as she enters the car.
The Countess - S1-E4
Plot hole: Rockford and Carl Brego are punching and kicking each other on the beach. Someone shoots him down with a rifle. The INSTANT Rockford goes to check out if he's still breathing, two people randomly happen to walk on him popping over from behind a rock as they were having a super casual and amused chat, but see Rockford by the shirtless brute and make a horrified face. Later in the episode the two identify Rockford and say that it looked like the two were fighting. Their facial expressions at the time don't make sense as depicted. Even if we assume that they did not see anything at all and they played it up/filled the blanks in their mind later, the two are not deaf and yet they were not perturbed or curious in the slightest after the loud bang of a gunshot. The way the scene was shot, the only thing tipping them off about anything was seeing Rockford over the corpse (which had barely a small dot of blood visible at the time and would hardly tip anyone off at first sight). (00:18:45)
The Countess - S1-E4
Factual error: Two cops (the bowtie guy that cuffs Rockford and the one that watches him being taken away from his trailer) report to HQ saying that the protagonist is a suspect for a 157, to which Rockford reacts saying he did not murder anyone (and it is in fact what he is accused of). But homicide is in CA police code 187, not 157. A 157 is an entirely different felony. (00:21:00)
The Countess - S1-E4
Other mistake: The first view of The Countess from Rockford's camera is at an impossible angle that does not match the position on the terrain (nor the footage we see later). (00:03:30)
The Dark and Bloody Ground - S1-E3
Character mistake: Clyde Russell tells Rockford to meet him at his place in "Ambazac Road in Bel Air." The name of the street in real life is Ambazac Way. (00:38:20)
Backlash of the Hunter - S1-E1
Continuity mistake: Rockford goes to police to ask Dennis Becker about the case. He leans against the wall as they chat, but his left hand is blatantly at different height in the two different angles that alternate. (00:24:30)
