Revealing mistake: Near the end of the film when Matthew is trying to destroy the pod "greenhouse," there is a shot where Elizabeth walks through. She is supposed to be naked, but if you look close you can see she is wearing flesh colored underwear. (01:55:30)
Revealing mistake: A car is driven off a dock into a body of water. Before the car hits the water, special effects shoot up about 10 different blasts of water.
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: Lou received Georgia's rather incriminating phone call. Only his bedside lamp is lit, supposedly, but when he opens the drawer of the nightstand the lamp is on, it casts a light on the wall above, revealing the presence of more sources of lights in the room. (00:07:00)
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.
