Trivia: Rusty Ryan is eating in nearly every scene he is in - on the DVD, there is a commentary by Brad Pitt (Rusty), where he says that during filming, he realized that since his character is so busy, he would have to eat whenever he got a chance, so he and the director decided to have him eating in every scene.
Trivia: Don Cheadle's billing/crediting in the movie was of significant dispute. Cheadle wanted to be mentioned above the title at the end of the movie - "pre title credits" - as a featured actor, along with Clooney, Pitt, and Damon, as opposed to being mentioned after the credits with the remaining cast members. His ask was refused by the director, and in response to that refusal, Cheadle said that he didn't want to be mentioned anywhere in the credits if he couldn't be granted pre-title credits. Cheadle's ask was granted in both Oceans 12 and Oceans 13, and he is mentioned before the title at the end of each movie.
Trivia: The order in which people left the fountain was completely improvised - Steven Soderbergh just told the actors to leave in whatever order they felt was right.
Trivia: When Benedict is in the vault, you can see a SWAT team member behind Benedict. It was supposed to be Brad Pitt (Rusty Ryan), but Steven Soderbergh didn't want the audience recognizing Pitt, so the filmmakers had George Clooney (Danny Ocean) come in and put on the helmet and walk behind Benedict.
Trivia: The "TeenBeats" Rusty is teaching to play poker go uncredited. They are Joshua Jackson (best known as Pacey in "Dawson's Creek," a TV teen drama), Holly Marie-Combs (best known as Piper in "Charmed," a TV drama), Shane West (best known as Landon in "A Walk to Remember," a film), Barry Watson (best known as Matt in "Seventh Heaven," another TV drama) and Topher Grace (best known as Eric on "That 70's Show," a TV comedy).
Trivia: The elevator is actually a card board prop because the casino was too busy to have an elevator held up for the filming.
Trivia: In the theatrical trailer when Danny Ocean is asked by the parole board what he thinks he will be doing when he gets out of prison, he says "well how much do you guys get paid?" This is never shown in the film. The producer asked actual parole board members what would happen if a convict asked this question during a parole hearing, and the board members said they would instantly deny parole.
