Corrected entry: Near the end of the movie, the three main characters are handcuffed behind their heads. In the next shot, there are no handcuffs and they are moving their arms freely.
Corrected entry: Near the end of the movie when Jennifer Aniston closes the blinds, she isn't wearing examination gloves but when the scene goes to Dale then back to her she is wearing gloves.
Correction: Enough time goes by between shots, and she herself (since she does this for a living) could be good at getting them on and off quickly, as well as Dale recounting this in flashback. There are sufficient gaps in time to explain that.
Not enough time passes. After she closes the blinds, she's off camera for about 6 seconds, but when it cuts back to her, she's still by the door, which she had closed during that time but isn't near any gloves. Then the next time she's only off camera for about 2 seconds, but during that time has moved closer to Dale and the patient and she has gloves on.
Correction: In the mentioned scene you can hear what sounds like handcuffs but you dont see the handcuffs been put on. You can even see the left officer reaching for his handcuffs which are on his back and in a following shot where the officer is holding the suspects hands (one the left)but there are no cuffs, just before the navguide voice of "gregory" kicks in. Ergo, they were not cuffed before the shot without handcuffs.
