This is the haunting montage from Alan J. Pakula's great paranoid political conspiracy thriller, The Parallax View (1974). In this scene, the protagonist, portrayed by Warren Beatty, is given a visual psycholical test by the Parallax Corporation - an organization that recruits and grooms assassins. The movie audience sees what Beatty sees. The combination of imagery and music is mesmerizing. The music was composed by Michael Small. YouTube link #1YouTube link #2Wikipedia articleDVD Talk article
