Audio problem: Volkswagen Beetles had a very distinctive "putt-putt" engine noise. In every scene with the bad guy following Ryan and McBride in a VW Beetle, the sound effects dubbed in post-production belong to a much larger, standard American car, and not to a VW at all. (00:26:00)
Revealing mistake: Not only is the stunt double's face visible in several shots during the apartment fight scene, the man is also noticeably taller and heavier than Robert Wagner, and is wearing a really bad wig.
Continuity mistake: The package containing the camera changes size and shape between the opening scene, where Barnes drops it into a mailbox, and the scene where it arrives at Auden's office.
Continuity mistake: During the car chase, Ryan pursues the kidnappers up a hill past two parked VW vans. When the camera angle reverses, one of the two vans has disappeared. (00:12:15)
Continuity mistake: At the carnival, Pete's cotton candy changes shape and doubles in size between takes. (00:24:30)
Whatever Happened to Carol Harmony? - S2-E23
Continuity mistake: After Pete and Mac chase the guard dogs out, the mansion's double gates close themselves between one shot and the next. (00:23:00)
