The music video for "American Idiot" features the band playing in a warehouse against a green American flag (a reference to the name of the band). In the middle of the video, the band is seen playing at different speeds (fast or slow-motion). During the bridge, the stripes of the flag melt onto the floor. The band is then sprayed by a green liquid from amplifiers next to the flag. At the end, the band drops their instruments and leaves.
