Walter Mortimer Mirisch (November 8, 1921 – February 24, 2023) was an American film producer. He was the president and executive head of production of The Mirisch Corporation, an independent film production company which he formed in 1957 with his brother, Marvin, and half-brother, Harold. He won the Academy Award for Best Picture as producer of In the Heat of the Night (1967). Life and career Early years Born to a Jewish family in New York, Mirisch was the youngest of three sons born to Josephine Frances (née Urbach) and Max Mirisch. His siblings included film producer Marvin. His father emigrated from Kraków, Poland in 1891 at the age of 17, arriving in New York City where he worked as a tailor. His mother was the daughter of immigrants from Hungary and Poland. His father was previously married to Flora Glasshut with whom he had two sons; she died of cancer at the age of 40.

In 1942, he received a BA degree from the University of Wisconsin–Madison and the next year he graduated from Harvard's Graduate School of Business Administration. He produced his first film, Fall Guy (1947), for Monogram Pictures. Career At the age of 29, Mirisch became production head at Allied Artists Studio, initially only a division of Monogram, with some 30 films to oversee.

Among other films, he supervised the productions of Invasion of the Body Snatchers, Friendly Persuasion (both 1956), and the Billy Wilder-directed Love in the Afternoon (1957).
