Revealing mistake: Within hours of being shot in the leg and having the bullet dug out without anesthetic (unless a slug of whiskey counts), Kimble is not even limping. (00:15:00)
Revealing mistake: During the race through the desert in Annie's Jeep, the rear-screen projection couldn't be more obvious. In the supposedly speeding vehicle, Annie's hair is blowing slightly, but Kimble's never moves at all. (00:35:30)
Death Is the Door Prize - S4-E2
Revealing mistake: Marcia demonstrates an early home video recorder at the trade show. Her camera set-up should record her test subjects from a lefthand angle. But her tapes show them all from a righthand angle - the position of the actual studio camera. (00:15:00)
Right in the Middle of the Season - S4-E11
Revealing mistake: When Kimble exits the police station and closes the door, the set wall wobbles. (00:19:05)
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.
