Howard Green Duff (November 24, 1913 – July 8, 1990) was an American actor of film, television, stage, and radio.
He graduated from Roosevelt High School in Seattle in 1932, where he began acting in school plays after he was cut from the school basketball team. Thereafter, he worked locally in the theater in Seattle until he entered the United States Army Air Corps during World War II, where he was eventually assigned to their radio service. He announced re-broadcasts prepared for the Armed Forces Radio Service (AFRS). In this role, he served as the announcer for the drama Suspense, dated March 16, 1943.
Duff's most memorable radio role was as Dashiell Hammett's private eye Sam Spade in The Adventures of Sam Spade (1946–50). With his TV and film career starting to take hold, he ultimately left the program in 1950 at the start of its final season; Stephen Dunne took over the voice role of Spade.
Duff was signed to a long-term contract with Universal, and made his film debut alongside Burt Lancaster as an inmate in 1947's Brute Force. The movie was produced by Mark Hellinger and directed by Jules Dassin, who gave Duff a bigger role in their next film, The Naked City (1948). He subsequently reunited with Lancaster for the family drama All My Sons (also 1948), based on the play of the same name by Arthur Miller.
Duff appeared in the 1952 film That Kind of Girl (aka Models Inc), and also featured in Spaceways, and Roar of the Crowd (both 1953), the latter for Monogram Pictures, which ultimately made Jennifer (also 1953), the second movie in which he starred alongside his wife.
His other film appearances beside his wife; Don Siegel's Private Hell 36 (1954); Lewis Seiler's Women's Prison (1955), and Fritz Lang's While the City Sleeps (1956) continued Duff's successful run of movies during the 1950s.
In addition to his movie roles, Duff also experienced success in television, with appearances in the 1950s series The Star and the Story, Climax! and Crossroads. From January 1957 to July 1958, he appeared with Lupino in the CBS sitcom Mr. Adams and Eve, which revolved around the private lives of two fictitious film stars Howard Adams and Eve Drake. They also served as producers.
Other TV roles included an appearance in NBC's western series Bonanza, playing a young Samuel Langhorne Clemens in his early life in the West as a satirical and crusading journalist, in the first season episode "Enter Mark Twain". Duff also featured in episodes of numerous TV series during the 1960s including The Twilight Zone, Burke's Law, The Eleventh Hour, Mr. Novak and Batman (the latter in an episode entitled "The Entrancing Dr. Cassandra", alongside wife Ida Lupino).
Duff had the lead role in the short-lived TV series Dante (which ran for only one season; 1960–61), but found greater success as Detective Sergeant Sam Stone in the ABC police drama Felony Squad (1966–69). Duff appeared in all 73 episodes of the series during its three season run, alongside his co-stars Dennis Cole and Ben Alexander. He also directed one episode; "The Deadly Abductors".
Duff also directed 7 episodes of the 1960s TV sitcom Camp Runamuck.
Duff continued to make guest appearances in TV series during the 1970s including The Streets of San Francisco and The Rockford Files amongst others, and also featured in the TV movies A Little Game (1971) and Snatched (1973). In 1971 Duff appeared as Stuart Masters in "The Men From Shiloh" (rebranded name for the TV western The Virginian) in the episode titled "The Town Killer."
Duff was part of an ensemble cast in the 1978 comedy film A Wedding, and had a prominent role as the attorney to Dustin Hoffman's character in the Academy Award-winning Kramer vs. Kramer (1979). In 1980 he played Charles Slade in the 1980 mini series The Dream Merchants
Duff portrayed villain Jules Edwards in Part 1 of the 1981 mini-series East of Eden, and was part of the main cast in the TV series Flamingo Road (1980–82), appearing in all 38 episodes of the show.
He continued to make guest appearances in TV series during the 1980s, including Charlie's Angels (1980) (as bumbling private eye Harrigan in the episode "Harrigan's Angel"); Murder, She Wrote (1984), Magnum, P.I. (1988) (as Capt. Thomas Magnum, II, the grandfather of main character Thomas Magnum, played by Tom Selleck), and Dallas (also 1988). Duff also had a recurring role as Paul Galveston during the sixth season of Knots Landing (1984–85), appearing in 10 episodes. He returned for one more episode in 1990.
Although Duff made few film appearances during the 1980s, he did have a prominent role in the 1987 thriller No Way Out, alongside Kevin Costner and Gene Hackman. In 1990, shortly before his death, Duff made his final acting appearances in the TV series Midnight Caller and The Golden Girls, and the film Too Much Sun.
After he was listed in Red Channels as a communist subversive in 1950, he lost his radio work and might have forfeited his entire career had it not been for his marriage. Duff and Lupino had a daughter, Bridget Duff (born April 23, 1952). The couple separated in 1966 but did not divorce until 1984. He subsequently married Judy Jenkinson. Like former wife Lupino, Duff was a staunch Democrat.
