Revealing mistake: When the teenage guy is getting attacked by the shark, the shark slams him up against the boat. He attempts to climb back on the boat and the shark pulls him down and the guy rips some wood from the edge of the boat. You can see the cut away part of wood that will be ripped off before he actually rips it off. (01:11:05)

Revealing mistake: Jackie is so ecstatic at the idea that her boyfriend is going to work at her friend's estate that she kisses him without watching the road. Since she is not paying attention, the car nearly hits the hedge at one side of the road, and she does a last minute swerve ending up cutting through a lawn before she can get back on the road again. During this maneuver which should be spontaneous and unplanned, you can see dirt skidmarks on the asphalt in front of the car from previous takes and a clear pathway through the lawn. (00:07:30)
Revealing mistake: Watch carefully during the fight scene between Billy and Rifki, you can see the stuntmen a few times.

Revealing mistake: Towards the beginning of the film, when Hannay has been arrested for the murder of Scudder he is being interviewed by Chief Superintendent Lomas. Hannay removed the bullets from Scudder's pistol whilst he was staying in his apartment, and Lomas is shown putting them on the table. One of the bullet casings has a hole drilled through the center of it, a typical method used to identify inert rounds as being safe to handle.
Revealing mistake: When Caroline (Mia Farrow) is hanging off the broken bridge railing, in the wide angles she is replaced by an obvious stunt. Furthermore, when David rescues her, the stunt woman is always acting calmed and natural, even helping David, as opposed to the close-ups of Farrow, nervous and trembling.
