Researching the Real Las Vegas
Scorsese and screenwriter Nicholas Pileggi spent months interviewing former casino executives, pit bosses, and mob associates to capture the authentic language and rituals of the gambling world. Pileggi's book Casino: Love and Honor in Las Vegas was based on the true story of Frank 'Lefty' Rosenthal. The production consulted with former casino employees to ensure accurate dealer procedures and surveillance techniques.
Real locations, such as the Riviera and Landmark casinos, were used before their demolition. This commitment to research gave the film its documentary-like texture and made the fictional Tangiers feel disturbingly real.
