Video
The video was directed by Francis Lawrence.
Brian: "We purposely aren't in it. (...) We told them that we were tired of dancing around like five people playing a punk rock song and put together a video that has nothing to do with us and actually does deal with the visual images, actually supports the lyrics much more accurately."
Trivia
