Nehemiah Persoff made a few appearances in The Untouchables series as Guzik, Bugs Moran is played here by Harry Morgan. Before going into the booze business Moran learned his criminal trade as a heist man and Guzik needs him to bring in liquor because The Untouchables are doing such a good job in shutting down his stills and club owners are buying from independents.
This episode as many of The Untouchables had absolutely no relation to reality. But Guzik by all accounts was a man with a convoluted Machiavellian streak to him. He shows it here and it proves his undoing.
The scenes with Persoff and Morgan crackle as they would have if the real Bugs Moran and Jake Guzik ever were in the same room and had no weapons. For that alone you should see this Untouchables episode.
