The band's history to that point has been documented in the documentary film "Anvil! The Story of Anvil", released in 2008. "Rolling Stone" called the movie "the year's most praised rock doc." The band played "Cat Scratch Fever" with Slash and Anthrax's Scott Ian at the Sundance Film Festival, where the movie premiered. The high praise for the movie put Anvil back into the public consciousness, propelling them to play several festivals, including the Download Festival in 2009 at which they headlined the Tuborg stage.
