Visible crew/equipment: Filming crew reflected on Paul's glass during the meal.
Visible crew/equipment: When Jules and Nic are in the bathroom, the camera pans around the room and the filming crew is reflected on the glass window by the tub.
Other mistake: In the middle of the movie, there is a scene with the two moms on the couch talking. One mom (red hair lady) wears a necklace with a charm that says "love." There are two camera shots in this scene, one looking directly at her, and another from over her left shoulder. Depending on the shot, the 'love' charm is either visible or tucked under the top of her shirt. This swaps back and forth.
