Born in Chicago on June 12, 1929, Lefty grew up at the track. He had a reputation as a master odds-maker. Starting in 1950, Rosenthal ran the biggest illegal bookmaking office in the U.S.
In the 1970s and ‘80s, Lefty Rosenthal ran four at the same time for the Chicago mob: the Stardust, Hacienda, Fremont, and Marina. In Casino, Rothstein only runs one casino. The interiors were filmed inside the Riviera while the exteriors were shot in front of the Westgate, which was the Las Vegas Hilton during the events of the film. Even the casino in the movie, The Tangiers, is a fake name for the Stardust.
