LEM BANKER came to Las Vegas when the town was still run by the mob. Lem quickly became connected to many of the unruly types that ran Vegas upon his arrival to the desert in 1953. Banker ran a couple of sportsbooks and became good friends with Lefty Rosenthal the man Robert De Niro's character is based on in the film "Casino."

But Lem didn't truly make his mark as a gambler until the 1980s behind a team of bet runners and a network that made him privy to inside information on injuries well before the bookmakers could adjust their lines. When Banker would receive injury information he would pounce and hit Vegas Sportsbooks and bookies across the nation--getting 'The Best of It.' Lem will point out what he did then couldn't be done today because of all the social media and Don Bets software which allows sports books to copy betting lines eliminating a lot of the bargain shopping that Banker parlayed into riches. 

Although, Banker was a highly successful gambler, the film demonstrates the perils and pitfalls for a lifelong gambler.
