Nichols also chose the music by Simon and Garfunkel. When Paul Simon was taking too long to write new songs for the film, he used existing songs, originally planning to replace them with newly written ones. In the end only one new song was available, and Nichols used the existing previously released songs. At one point, when Nichols heard Paul Simon's song, "Mrs. Roosevelt," he suggested to Simon that he change it to "Mrs. Robinson." The song won a Grammy after the film was released and became America's number 1 pop song. Nichols selected all the numerous songs for the film and chose which scenes they would be used in. The placement and selection of songs would affect the way audiences understood the film. Even actor William Daniels, who played Hoffman's father, remembers that after first hearing the songs, especially "The Sound of Silence," he thought, "Oh, wait a minute. That changed the whole idea of the picture for me," suddenly realizing the film would not be a typical comedy.
