The mockumentary-style music video for "Smiley Faces", directed by Robert Hales shows a music historian (played by Dennis Hopper) and an A&R executive (played by Dean Stockwell) being interviewed about whether or not Gnarls Barkley (the person) exists and pondering over whether Barkley is behind the music scene.
