Wild Zero (2000 Japan)
Only legendary Japanese garage rock band Guitar Wolf can stand between a race of aliens from destroying earth with an army of zombies.
Wild Zero is equal parts Rock-N-Roll High School, Plan 9 from Outer Space, and Night of the Living Dead. It boasts an amazing soundtrack (equal parts Japanese and American bands), a cast that is long on "cool" and short on Oscar potential (just like a B-movie should be), and an excellent mix of camp and schlock horror.
Featuring the band Guitar Wolf (a real band by the way, who lack a certain level of musicianship, but more than make up for it with rock-n-roll attitude) and Ace (Masashi Endo, who does have acting talent) the movie takes us on a ride through an Ed Wood/George Romero wasteland that features a hell bent for leather biker attitude. The plot is no thinner than any other B-movie, and actually carries a rather broad minded message about acceptance and values. (IMDB shyquixote)
