David J. Stewart (January 8, 1915 – December 23, 1966) was an American Broadway, film, and television actor.
Born Abe J. Siegel in Omaha, Nebraska, Stewart was known primarily as a New York stage actor. However, he also made several appearances in movies and on television before his death at age 51 in Cleveland, Ohio, following surgery.
Stewart's played Louis "Lepke" Buchalter, the real-life crime boss whose activities were central to the film Murder, Inc. (1960). He also co-starred in the rockabilly-themed film Carnival Rock (1957), for which director Roger Corman, hoping to give the film some gravitas, recruited him from New York, a point noted by actor Ed Nelson in an interview with film historian Tom Weaver.
Stewart's strong, aquiline features were well-suited to the stage but limited his on-screen roles to character parts. This may have frustrated the actor. According to Nelson, Stewart looked at him on the set one day and remarked, "My God, what I couldn't do with a face like that."
His other film roles were small, and, while he appeared often on live television in the 1950s, his only TV roles that remain accessible were on Have Gun Will Travel, One Step Beyond, Alfred Hitchcock Presents, Voyage to the Bottom of the Sea, The Man From U.N.C.L.E. The Untouchables and Naked City.
The Hitchcock episode, "The Sorcerer's Apprentice" concerns a magician (played by Stewart) whose act includes sawing his wife in half. The episode was deemed too gruesome by the NBC Television Network and sponsor Revlon, which cancelled the network broadcast. The episode was later syndicated to local stations. An infamous footnote in the series' history, the episode fell into public domain, and is often included in value-priced Hitchcock DVD collections.
