Stephen Falk "Steve" Krantz (May 20, 1923 – January 4, 2007) was a film producer and writer, most active from 1966 to 1996.
Born in Brooklyn, New York, Krantz graduated from Columbia University and went on to serve in the U.S. Army Air Forces in the Pacific during World War II as a second lieutenant.
He worked as a comedy writer for Milton Berle and Steve Allen. His later years were devoted to the production of animated cartoons in Canada. After firing Shamus Culhane from the animator's supervising director job on Rocket Robin Hood, director Ralph Bakshi and background artist Johnnie Vita were brought to Toronto, not knowing that Krantz and producer Al Guest were in the middle of a lawsuit.
Failing to reach a settlement with Guest, Krantz told Bakshi to grab the series' model sheets and return to the United States. When the studio found out, a warrant for Bakshi's arrest was issued by the Toronto police. Bakshi's animation studio, Bakshi Productions, took over Rocket Robin Hood and another Krantz-produced series, Spider-Man, beginning Krantz' working relationship with Bakshi.
