A feature of many casinos are the sports books (facilities where betting takes place on horse races and other sporting events). Frank Rosenthal, a US horse racing handicapper who realized that bookmaking could be a huge money-spinner for casinos, opened the first race and sports book at the Stardust Casinos in Las Vegas. Its success resulted in race and sports books being introduced to The Strip. The story of Rosenthal's life was portrayed in the movie "Casino".
