For the second time George C. Scott plays a character originated by Lee J. Cobb. Cobb in 12 Angry Men (1957) and Scott in this remake both play Juror #3; and Cobb played Lt. Kinderman in The Exorcist (1973) (directed by 'Friedkin, William', like this film), as did Scott in the sequel The Exorcist III (1990).
Filmed in sequence.
There are only two of the jurors that are identified by name; #8 as Mr. Davis and #9 as Mr. McCardle. All but one of the jurors are identified by their profession; #1 High School Football Coach, #2 Bank Teller, #3 Messenger Service Owner, #4 Stock Broker, #5 Hospital Nurse, #6 Painter, #7 Marmalade Salesman, #8 Architect, #10 Car Wash Owner, #11 Watch Maker, and #12 Advertising Agent.
Screenwriter Reginald Rose updated his own 43-year-old teleplay, racially integrating the cast of jurors for the first time. When asked in an interview why he didn't cast some of the jurors as women, he jokingly (but accurately) quipped, "Then the title would have to be changed to '12 Angry Persons,' and it wouldn't be as effective."
Jack Lemmon appears in Mister Roberts (1955) with Henry Fonda, in which he takes over Fonda's position of Morale Officer when Fonda is transferred off the USS Reluctant. In the 1997 remake 12 Angry Men (1997) (TV), Lemmon plays the same juror that Fonda played in the original 12 Angry Men (1957).
