The actual place where Dutch Schultz was killed, was the Palace Chop House, 12 E. Park St, Newark, NJ. The building was torn down in 2008.
Margaret Field, listed in the credits by her married name Maggie Mahoney, wife of actor Jock Mahoney, is perhaps best known as the mother of actress Sally Field.
This is the second of three appearances Lawrence Dobkin makes in the series, each time playing Dutch Schultz. The other two appearances occur in Vincent 'Mad Dog' Coll (1959) and Jack 'Legs' Diamond (1960).
Marion Ross, playing a loving mobster's wife in this episode, would go onto play a different class of wife in the TV sitcom Happy Days (1974) where she played the lovable Mrs. Cunningham.
Adjusted for inflation, the $30 Flaherty slips to Rosenkrantz in 1935, the year the action takes place, would equal approximately $64 in 1959, the year the show was originally broadcast. In the year 2024, that amount would equal approximately $675. The $50 that Schultz offers Flaherty would equal approximately, $106 in 1959 and $1,125 in 2024.
