I love music documentaries. From Gimme Shelter to Metallica – Some Kind of Monster they are always a lot of fun to watch especially when it’s about music you like. Then you’ve got your classic underdog docs like Murderball and The King of Kong. Combine them together and you’ve got Anvil! The Story of Anvil, a documentary about the biggest heavy metal band to never make it big. I’ve been reading about this film for a while and it looks like it’s going to hit theaters on April 10. Enjoy the trailer above and enjoy the film when it comes to your town.
