Given an uncredited bit part as one of the hoodlums in this show, Charlie Picerni is perhaps better known in the industry for his work as a stunt coordinator/director, as well as performing stunts and acting as stunt doubles for other actors. His work in Die Hard (1988) and the franchise that followed made him a star in the field of movie stunts. The actor who plays Lee Hobson in The Untouchables (1959) is in real life his brother.
Although a prolific actor in movies and on TV, mostly in minor roles, and taking on another minor, albeit uncredited, role in this show, playing Flip the whiskey runner, Paul Mazursky is perhaps best known for his writing and directing: Down and Out in Beverly Hills (1986) and Bob & Carol & Ted & Alice (1973) being just a couple of the titles he is associated with in these capacities.
Elito Ness tells Fr. Gregory to beware of Greeks bearing gifts. He's paraphrasing a line from the story of the sack of Troy by the Greeks written by the ancient Roman poet Publius Vergilius Maro in his epic poem "The Aeneid," Book II, line 49, wherein, on the beach outside the gates of Troy, Laocoon warns his fellow Trojans not to trust the gift of the wooden horse left for them by the Greeks. He says, 'timeo Danaos dona ferentis', literally translated from the Latin as 'I fear Greeks bearing gifts'.
Adjusted for inflation, the $140/case price that Flip, played by Paul Mazursky, seeks for delivering the Canadian Gold whiskey would equal approximately $3,200 in the year 2024.
