Check out "Diamonds Are Forever" (Sean Connery--the REAL Bond!). If you look closely at some of the overhead shots of the scenes filmed on the casino floor of the Circus Circus, you can clearly make out the actual "ringmaster" series chips. I saw 1.00s & 5.00s, but couldn't discern the 25.00s or 100.00s. The movie also has a great chase scene through downtown, with many historic clubs shown.
