Continuity mistake: All of the SWAT team members are together in a group going down on the elevator. Yet, when Rusty is looking back on the events, Sol is moving slowly and behind the rest of the group because he's getting hurt. (01:35:30 - 01:40:10)
Continuity mistake: In the scene where Tess is stepping out of the elevator and she runs into Terry, her hair is in a sleek, perfectly-styled French twist. Then in the next shot when she turns to him and says, "You of all people should know, Terry, that in your hotels, there's always someone watching." Her hair looks messy and disheveled. (01:44:20)
Continuity mistake: At the end of the film, when all eleven members are in a line looking at the big fountain, and they each in turn walk off, the man on Rusty's left looks at him, then looks away again. But when the shot changes to the opposite direction, the same man looks away again. (01:48:00)
Continuity mistake: When Rusty is talking to Linus, giving him instructions, he is constantly eating an ice cream with a spoon. When he sets the ice cream down and leaves the room the entire ice cream is still there, two untouched scoops of ice cream. Obviously the cup was refilled during a cut.
Continuity mistake: When Danny and Rusty try to convince Reuben to join the team, the first shot from behind Reuben shows him picking up a fork, but in the next shot, his hands are gesturing in front of him.
Continuity mistake: In the race between the big truck and the radio controlled little truck, the position of the tires relative to the start line changes between scene cuts.
Continuity mistake: When Danny leaves prison after his probation violation and meets Rusty, he is wearing the tuxedo he was arrested in and has an untied bow tie. The location of the untied bow tie changes several times.
Continuity mistake: Danny's face changes quite a bit between being beaten up and being put in the police car. Stubble and bruises vanish suddenly.
Continuity mistake: When Rusty and Danny are at Reuben's house talking to him over lunch, the three objects to the right of Reuben on the table (one of them is black, the other two are gold) change position between shots.
Continuity mistake: When Livingstone (pretending to be the Home technician) is trying to find his way out after hooking into the Casinos security systems, he is seen soaked with sweat on his shirt. A second later, when the Casinos security man is approaching him, the sweat stain has almost disappeared.
Continuity mistake: Towards the end of the film, there's a scene where Tess runs into Terry as she's getting off the elevator to go find Danny - Her hair is smooth and styled into a French twist. As she's walking down the steps into the casino, Terry calls after her and she turns to face him - This time, her hair is wavy and in a different style.
Continuity mistake: Danny says the elevator needs a 6-digit code that is changed every 12 hours. Later when Linus presses them, he enters 1138, which is a 4-digit code. Matt Damon mentions this on the commentary.
Continuity mistake: When saving Linus (Damon) from guards chasing him at the lab, rear van door swings wildly, acrobat grabs it from the inside with his left hand and slams his hand in the door. He reacts by grabbing his injured right hand.
Suggested correction: He grabs the door with his right hand, not his left. He's sitting with the door to his right, if he reaches across his body to grab the door with his left hand, then his thumb would be on top. But it's not, so you know it's his right hand.
