 While the movie begins by stating it is based upon a true story, it  never names the actual casino involved. The Tangiers casino is  fictional. The story is actually based upon the history of the  Stardust casino, a fact well documented in the Vegas history books.  Scorsese discreetly documents this fact via the soundtrack, in which  the song "Stardust" is heard three different times. An instrumental  version plays during Ace and Gingers wedding and a vocal version is  heard during the scene where Remo asks Marino if Nicky and Ginger  are having sex and also during the very end of the final credits.
