A piano piece composed by Richard Wright of Pink Floyd for the final 'violent scene' went unused, but was later reworked by the band as "Us and Them" on their album "Dark Side of the Moon". Remembering the scoring sessions for this film, members of Pink Floyd later commented that Michelangelo Antonioni was very difficult to please. In fact, Michelangelo Antonioni's original ending was a shot of an airplane sky-writing the phrase "Fuck You, America," which was cut by MGM president Louis F. Polk along with numerous other scenes.
