The car used by Tim Bart (Dix) during the making of his film as a gangster about to hold up a bank and the car used later by the three robbers in an actual hold-up attempt bears the same license plate number 6W 4079.
Although set in the transitional Hollywood silents-to-talkies period of late Twenties/very early Thirties, many of the celebrity doubles show up in costumes inspired by roles they didn't play until middle Thirties.
Movie company is supposedly shooting a scene at an actual bank at corner of Hollywood and Vine, but in reverse angle shots, it is clear that buildings on other side of street are fake sets.
