He often took on Hollywood genres with a revisionist's eye, de-romanticizing the Western hero in 1971's "McCabe and Mrs. Miller" and 1976's "Buffalo Bill and the Indians, or Sitting Bull's History Lesson," the film-noir gumshoe in 1973's "The Long Goodbye" and outlaw gangsters in "Thieves Like Us."
"M-A-S-H" was Altman's first big success after years of directing television, commercials, industrial films and generally unremarkable feature films. The film starring Donald Sutherland and Elliott Gould was set during the Korean War but was Altman's thinly veiled attack on U.S. involvement in Vietnam.
"That was my intention entirely. If you look at that film, there's no mention of what war it is," Altman said in an Associated Press interview in 2001, adding that the studio made him put a disclaimer at the beginning to identify the setting as Korea.
"Our mandate was bad taste. If anybody had a joke in the worst taste, it had a better chance of getting into the film, because nothing was in worse taste than that war itself," Altman said.
How we loved Robert Altman back in the early 1970s. I don't have time to write more now, but I want to say that he meant a lot to people in my generation. He had a long and brilliant career, but those early films have deep and great significance.
