Casino heist movies are a genre of their own. A charming crew, a hated casino owner, a vault full of cash, and a plan that works perfectly until it nearly does not. They are great fun, and almost nothing in them resembles how a casino actually protects its money.
Myth: the money sits in one giant vault
Real casinos handle cash constantly, in many places at once: the cashier's cage, the count rooms where table and machine takings are counted under camera, and armoured transport. There is rarely one magic room holding everything, and the amount on site at any moment is planned to be as small as practical.
Myth: you can loop the cameras
The dark domes in a casino ceiling, known as the "eye in the sky", cover practically every table, machine, door and cash route. Surveillance staff watch live feeds and record everything, and the system is designed with redundancy so that losing one camera, or one room, does not blind the operation. A laptop plugged into a cupboard does not end the night's recording.
Myth: security is all muscle
Most casino protection is quiet. Dealers follow strict procedures for handling chips and showing clean hands when they leave a table. Supervisors watch for unusual betting patterns. In Nevada, regulators keep a list of people banned from every casino in the state. The point is to notice a problem early, not to win a fistfight.
What films get right
They are right that casinos care about advantage players. Card counting at blackjack is not a crime in Nevada, but casinos can and do ask skilled counters to stop playing blackjack or leave. And they are right that the house usually wins, though in reality that is down to the built-in house edge on every game rather than a villain with a cigar.
None of this spoils the films. Knowing how hard the real thing would be makes the fantasy more fun, and the trailers, as we noted in A Short History of the Movie Trailer, have always sold the glamour first.
