In Ocean's Eleven (2001), the casino owner whose vault Danny Ocean plans to rob is Terry Benedict.
Andy García plays Benedict, the wealthy and tightly controlled owner of the Bellagio, the Mirage, and the MGM Grand in Las Vegas. Danny's plan is personal as well as financial: Benedict is dating Danny's former wife, Tess Ocean, played by Julia Roberts.
The central robbery targets the vault beneath the three casinos, where money from the properties is consolidated before being transported. This fictional casino empire is an important part of the film's premise, although the real Las Vegas properties have different ownership histories.
Terry Benedict is sometimes confused with Reuben Tishkoff, the former casino owner who helps finance the operation, or Rusty Ryan, Danny's chief partner. Benedict is the target and antagonist, not a member of the heist crew.
