In the film, Bud refers to a "Peggy Joyce" twice when talking to John about setting him up with dates. He is referring to Peggy Hopkins Joyce, a well-known actress, model, and dancer at the time, who had already married and divorced four (eventually six) wealthy men and led a lavish and scandalous lifestyle. At one point in 1928 she was so wealthy that she purchased the 127 ct. Portuguese Diamond for $373,000 ($5.3M in 2017). The diamond is in the Smithsonian's National Gem Collection.
The basic plot premise of this movie would be used in many other Warner Brothers movies such and Manhunt and Tiger Shark.
