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: When Danny is leaving the prison in the beginning the camera from the back shows him walking with his hands at his sides. The camera changes to a view from the front and his hands are now in his pockets. (00:02:12)
Factual error: The security cart that Yen hides in is supposed to be airtight. But when Rusty (Brad Pitt) closes the lid on the cart after Yen has entered it, the front left side pops back up slightly. That gap would prevent the cart from being airtight. (01:10:55)
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 Bruiser first punches Danny, Danny bends over to slap the table and Bruiser puts his hand on Danny's back. The camera angle changes and Bruiser now has one hand on Danny's back and the other on Danny's side. (01:18:40)
Revealing mistake: When in the vault, the Asian acrobat does a flip on to another structure. The flip has been digitally manipulated as his movements are very choppy and unnatural. (01:26:35)
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: 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.
Visible crew/equipment: After disabling the guards, Damon and Clooney go to open the vault. The camera's reflection can be seen on the vault door as the shot pulls back. You can also see the crew member operating it.
