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.
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)
Continuity mistake: When Rafe is shot at the end, the gun he was holding in his right hand disappears between shots. (00:45:15)
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 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)
Visible crew/equipment: When Gerard opens the precinct office door, its glass shows us several studio reflectors. (00:04:20)
Visible crew/equipment: When Kimble gets into the cab, the vehicle's shiny yellow side captures a reflection of the entire camera crew. (00:26:45)
Continuity mistake: Kimble walks out of Jean's apartment, leaving his bag behind. But in the very next shot, he's holding the bag as he comes out of the building. (00:48:25)
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: Kimble's nephew Billy is mistakenly listed as "Bobby" in the end credits.
Visible crew/equipment: The tailgate of Lloyd Chandler's station wagon, and the door of Gerard's car a few minutes later both capture reflections of studio lights and the camera crew. (00:04:50 - 00:07:10)
Continuity mistake: The one-armed man orders Chandler to get up off the ground. In close-up, we see him sit up. But in the very next shot, he's flat on his back and sits up again. (00:11:50)
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: 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)
Revealing mistake: The last scenes of the grand finale/climax occur in an abandoned amusement park that's supposed to be in inland Indiana. But several shots with the Pacific Ocean "lurking" in the background (despite the cameraman's best efforts to hide or avoid it), as well as palm trees, and ocean sounds intruding on the soundtrack, reveal that the actual shooting location was in Southern California. (00:37:15)
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.
