 While filming in Las Vegas, producer Dan Curtis (I) (qv) was  amazed at how oblivious the casino gamblers were to any events going  on around them other than gambling. So as a joke one day, actor  Barry Atwater (qv) (Janos Skorzeny) was asked to walk through the  Saharas casino in full costume and makeup to see if anyone noticed  him. He did this for over 40 minutes, and didnt even get a second  glance.
