This was Herb Edelman's first appearance in the recurring role of Lt. Artie Gelber, Jessica's contact on the NYPD. Interestingly, Gelber was about to retire from the force but he would return for seven more appearances.
Herb Edelman and Ken Howard have something in common. They are both ex-husbands of actress Louise Sorel.
At the ticket counter, Jessica is a victim of mistaken identity a la Hitchcock's Roger Thornhill in North by Northwest) (1959).
Again with the gunsel error. When Dashiell Hammett used this word, it meant homosexual, not thug. He was playing games with the censors in The Maltese Falcon. MSW uses the word to mean small-time gangster a lot.
