Visible crew/equipment: When Smith and Neo are fighting in the building Smith is knocked to the floor. When he gets up you can see the stage light in his glasses. (01:44:35)

Continuity mistake: When Trinity is meeting with the Frenchman, the olive in his martini changes. In the first close-up shot, he only has one green olive on the cocktail stick. From then on he has two, until he eats one. (00:19:50)

Revealing mistake: When Neo and Smith are fighting at the end of the film - when Smith knocks Neo into the rafters of the room they are in, you can see Neo's face, and it's obviously Keanu Reeve's stunt double. (01:44:30)

Revealing mistake: In the subway scene, when Neo gets slammed towards the wall (and crashes into it) it's visibly Keanu's stunt double.

Continuity mistake: In the scene where Bane has the scalpel to Trinity's neck, the bloody mark below it keeps disappearing and reappearing. The scalpel changes positions too as well as the blade itself changes. (00:52:55)
