Continuity mistake: On the skyscraper, when Neo and Trinity kill all of the soldiers, Agent Brown comes to the roof. Neo immediately draws his guns and fires until both of his clips are empty. After that, Neo drops his guns, just as Agent Brown aims at him. During Bullet-Time there are no guns on the floor. When he hits the ground, then the guns are left and right of his legs. (01:41:50)
Continuity mistake: When Anakin attaches 3PO's right eye, one shot has the eye in his left hand, then the angle changes and the eye is being applied with the right hand. (00:37:20)
Visible crew/equipment: Watch for the boom when the cigar girl's Volvo boat swipes the building (it's on the top left of the screen on the widescreen version).
Revealing mistake: During the bedroom scene with Felicity and Fat Bastard you can clearly see the air hose that fills his suit when he rolls over in the bed. (00:49:10)
Continuity mistake: In the scene in the library, when Evie is putting back the books. She leans over to put the book back, but it falls to the ground and she is balancing on the ladder. When the camera cuts back to show the whole ladder, the book is nowhere to be found on the floor. (00:13:00)
Continuity mistake: Look carefully when they transport to the Mexican Restaurant. Her night dress is unbuttoned at the top but mysteriously closes in a matter of seconds.
