Visible crew/equipment: As Will and Jack duel up top in Brown's shop, in two close-up shots a large plank is visible at their feet with two long black marks along each side detailing where the beams are supposed to be, so that Orlando Bloom and Johnny Depp know where to land as they supposedly leap from beam to beam and feign keeping their balance. (This is ONLY visible on the video version.)
Revealing mistake: When Karen rips open the wrapping on her gift from Harry, in the close-up of the CD as she holds it with her right hand, it is blatantly obvious that it is not Emma Thompson's hand. Just compare it with the earlier shot of her hand when she sneaks a peak at the card signed - "Sorry I'm such a grumpy bugger.. Bad Harry." (01:27:45)
Continuity mistake: When Tapia is giving the mural artist a dressing-down, his daughter has a book in one hand for most of the scene, but when the shot changes to one from above Tapia and his daughter, the book changes to the other hand. (02:03:15)

When the sniper pushes her away, the stunt double for Natalie falls to the floor and the tattoo is missing.
Continuity mistake: At the end when Bob walks out to see who played the song, there is an order pad sitting near the end of the counter. When Bob walks out with Walt the pad has turned into what looks like a menu and moved to the very corner. (01:42:55)
Continuity mistake: NBA Finals-Game 1. Andie wants Ben to buy her a Coke. During this scene, the camera cuts back and forth between Andie and Ben, and the basketball game. When Ben first looks at the game clock there is a little over a minute left in the game. He rushes to get her soda, and when he gets back, she says she wanted Diet Coke. There is a shot in this sequence where the camera is filming the basketball action, and you can see the game clock with over 7 minutes remaining, even though they are supposed to be nearing the 30 second mark. (00:33:35)

The first shot sees the whole car come onto the road, where there is a double unbroken line in the middle of it. The shot changes to Buddy and Dave in the car. Watch through the back windshield. The double unbroken line has turned into a single, broken line. (01:07:35)
Visible crew/equipment: When Peter is at the golf course with Mrs. Arness, you can see the golf cart behind them. In the next scene, there is a woman sitting in it and she appears to be the stand in for Mrs. Arness. (Confirmed on the audio commentary). (00:40:05)
