I happened to have visited Las Vegas (from So. CA) while filming was going on at Circus Circus. Outside the main entrance (probably all entrances as well) there was signage (posters on tripod easel stands) that advised all patrons that filming of Diamond Are Forever was underway inside Circus Circus and that by entering the building you were granting permission to have your likeness caught on film and used in the movie.

It was more an enticement than it was an advisement.

This of course was before I was a collector! Sure wish I had one of the posters.

ps. No, I was not caught on film and no, I did not see any filming. At the time I wasn't all that interested in filming, as being from So. CA you ran into it all the time.
