Continuity mistake: In the final scene with Andrew Beckett dying in hospital, he is wearing an oxygen mask. The LHS green strap is outside the mask when the mask is removed. When put back by Joe Miller it is on the inside of the mask - this would also impact on the flow of oxygen to the patient. The next time we see Beckett the green strap appears on the outside, but no one was near to move it. What is also strange is that Miller doesn't correct the position of the strap as it looks really odd.
Continuity mistake: Near the beginning of the movie, Andy is walking down the hall of his law firm - he has a pamphlet in his right hand and his briefcase in his left. Just before he passes a woman approaching him, he switches the pamphlet to his left hand. He then high-fives the woman; the shot changes to from behind him, and we see him letting go of her hand but the pamphlet is now in that hand.
Continuity mistake: There is a scene where the senior partners of Wyatt, Wheeler, Hellerman, Tetlow and Brown walk down a corridor of a 76ers basketball game discussing the lawsuit brought on them by Andrew Beckett. At one point they stop in the middle of the corridor (no doors are nearby)and the camera shot focuses on one of the partners. In the next shot a man comes through a set of doors right next to the partners and walks past them, interrupting them in the middle of their conversation,but there were no doors near them in the previous shot.
Continuity mistake: In the library scene, before Joe approaches Andy, we see him working. There's a pile of books on the table whose backs are turned away from the camera. Joe looks over to Andy who is briefly in the picture, and when the camera cuts back to Joe the pile is turned around and the backs are visible.
Continuity mistake: In the scene where Joe returns home after the costume party to hug his little girl, you can see that the time on his wristwatch is 1:29:43 as he picks her up out of her bed to give her a hug. Roughly 36 seconds later, after he has hugged her and told her that he loves her, he lies her back down in the bed. The second hand on his watch has not moved, the time is exactly the same.
