"Won't Back Down" is more industrial sounding than the rest of the band's catalog, which is partially due to the nature of the film, and also due to Bell having less than a week to write the song to meet Fox studios' deadline in order make the film and soundtrack. It is the first song played in the credits of the movie.
The "Won't Back Down" video found considerable airplay on MTV2 and Fuse TV. It features clips from the movie, and Fuel is seen playing from atop a building with a helicopter flying around in the background. Brett Scallions then enters the building and makes his way to the top floor while searching for Daredevil's signature cane weapon. As he advances, a SWAT team follows Scallions through the building. The video is included on the second disc of Daredevil.
Fuel's DVD includes a music video for "Won't Back Down," titled "Won't Back Down (Band Version)." This has all the clips from Daredevil removed.
