Robert Altman film from 1970. Same year as M*A*S*H and quite a few of the same cast, including Sally Kellerman's tits. Strange film. OK
Saw this in the theater when it came out. Bud Cort was in three oddball movies in a row in the early 1970s. First was The Traveling Executioner with Stacy Keach. I think I may be the only person on the planet who saw it. (Waiting for W+A...) Then Brewster followed by his best known movie, Harold and Maude with the great Ruth Gordon.
