Continuity mistake: The date of Helen Kimble's murder is given here as Sept. 19, 1961. Previous episodes, however, had established it as occurring on Sept. 17, 1960.
Continuity mistake: In flashback, we see the one-armed man kill Helen Kimble by striking her with a heavy lamp. All through the earlier seasons, though, we were repeatedly told that Helen had been strangled. (00:28:50)
Tiger Left, Tiger Right - S2-E6
Continuity mistake: Kimble's been kidnapped and held for ransom. He had nothing with him when he was taken, yet when he leaves the abandoned house with the kidnappers, he has a small suitcase. When they drop him off on the road, he doesn't have it. When, in the epilogue, he's shown walking, he's carrying a different, larger suitcase. (00:46:00 - 00:49:00)
Never Wave Goodbye (2) - S1-E5
Continuity mistake: In Part 1, Kimble worried about Gerard tracing him by a match he left behind. We got a close-up when he tore the match out of the book: it was the 3rd in a row of 5. But here, as he looks at the matchbook and worries again, the close-up shows the only match missing from the book is the 5th one. (00:02:00)
Continuity mistake: Throughout the show's early episodes, Helen Kimble's dress on the night she was murdered was described as blue or blue-gray. Here, in the flashback to the murder, she's wearing an evening gown that isn't blue or gray, but pink. (00:27:45)
Continuity mistake: Ralph's brother hits him over the head with a bottle, which shatters. When Kimble runs past the same spot a few shots later, though, the broken glass is gone. (00:43:30)
Continuity mistake: Dan tosses a silver dollar into the puddle of water and we see it sink. A few shots later, though, the coin is visible again, impossibly "floating" on the puddle's surface. (00:05:20)
Continuity mistake: The wine crates on Kimble's hand truck in the opening scenes shift positions by themselves between takes. (00:02:25)
Continuity mistake: Kimble and Chris are on a busy freeway with several other cars when a police car pulls them over. But when they stop, the other cars all vanish and the road is suddenly deserted. (00:36:50)
Continuity mistake: Kimble's wanted poster in this episode lists his birthplace as Beloit, Wisconsin. In every other episode featuring close-ups of the poster, Kimble's birthplace is Stafford, Indiana. (00:41:40)
Nightmare at Northoak - S1-E11
Continuity mistake: When Gerard leaves the cell block, Kimble is at the cell door with his hands on the bars. Next shot, as Gerard exits, the cell door is visible in the background, and Kimble is no longer standing there. But in an immediate cut back to the cell, he's back with his hands on the bars again. (00:35:35)
Never Wave Goodbye (2) - S1-E5
Continuity mistake: Gerard is rowing the life raft with his back to the shoreline. But in the next shot, he's instantly facing in the other direction as the waves begin tossing the raft. (00:41:30)
Continuity mistake: When Rowland's wife unfolds Kimble's wanted poster, the center crease is peaked toward her. But when we see a close-up of it, the poster has been folded the opposite way, with the crease pointing away from her. (00:41:45)
Smoke Screen - S1-E7
Continuity mistake: Dr. Kimble says here that he interned in New York. In "The Survivors," we were told that he interned at County Hospital in Fairgreen, Indiana.
The Shattered Silence - S4-E27
Continuity mistake: Kimble is wounded in the left arm. But at the end, as he makes his way down the mountain, he's holding and favoring his right arm. (00:49:00)
The Breaking of the Habit - S4-E19
Continuity mistake: Kimble was gimpy early in the episode, because he had been shot in the leg. During the episode he refuses any treatment. But near the end of the episode he is seen walking without a limp and in perfect health.
Dossier on a Diplomat - S4-E25
Continuity mistake: Kimble tells Hobart there's no new evidence that could get him another trial. But maybe Dr. Kimble is suffering from amnesia. In the past 3 1/2 seasons, he's uncovered no fewer than four potential witnesses who could provide new evidence in a second trial. (00:22:35)
The Breaking of the Habit - S4-E19
Continuity mistake: Kimble enters Sister Veronica's room, closes the door and walks toward her. Then the shot cuts to a closer angle, and he's closing the door over again. (00:31:55)
Continuity mistake: Rafe and Kimble escape handcuffed together. They break the linking chain with a rock: each then wears a single bracelet. But when he kneels to examine the dead deputy, Kimble is wearing a cuff with an intact chain and an empty bracelet hanging from it. (00:28:45)
A Clean and Quiet Town - S4-E3
Continuity mistake: The rear tires on Kimble's car get stuck in the sand and spin when he's trying to U-turn and avoid the roadblock. After the police order him to drive back to town with them, however, the car wheels somehow unstick themselves, and Kimble has no trouble at all driving out of the sand pit. (00:48:25)
Answer: Production vehicle models aren't in sync with the calendar year. The '65 Mustang began production in March 1964 and first sold in April 1964, before it was "introduced" the following year. I don't know which model was seen in the episode, but the 2+2 fastback was sold in September 1964. The 1964 film "Goldfinger" uses a 1965 Mustang as part of Ford's product placement. Basically, in the 1930's, FDR ordered automakers to release vehicles in the fall of the preceding calendar year "as a means of facilitating regularization of employment in the industry." Now, automakers can release new models as early as Jan 2 of the preceding year.
