In which Oscar category did the 1970 M*A*S*H film win?

The 1970 M*A*S*H film won the Oscar for Best Adapted Screenplay.

The award went to screenwriter Ring Lardner Jr. for adapting Richard Hooker’s 1968 novel, MASH: A Novel About Three Army Doctors. The film was not an original screenplay: its characters and central situation came from Hooker’s book, which is why the Academy placed it in the adapted category.

M*A*S*H received five Academy Award nominations, including Best Picture, Best Director for Robert Altman, Best Supporting Actress for Sally Kellerman, and Best Film Editing. It won only the screenplay award, despite becoming one of the biggest films of 1970.

The movie also received major recognition outside the Oscars. It won the Grand Prix at the 1970 Cannes Film Festival, an award later known as the Palme d’Or. Its success helped lead to the television adaptation, which premiered on CBS in 1972. The film and series share the M*A*S*H title and source material but have notably different tones and creative approaches.
