This full-length movie happens to be that Billy and Mandy special I aformentioned in my reviews for the videogame.
In this movie, the Grim Reaper, now powerless, has him, Billy, Mandy, and Irwin on a quest to find the mystic artifact, the Hand of Horror, before his high school rival the Boogeyman gets to it first. Beware of monstrous pirates, high-speed chases, creepy cyclopses, crude puppets, cyborg doppelgangers, tons of snot, a ferocious kracken, and a couple of good songs, too. You'll also note that some of the costumes and other stuff in this movie were big inspirations to the videogame.
Special features on this DVD include a full-screen and a wide-screen format of the movie. Plus, behind-the-scenes interviews with the voice actors of the movie and a bonus cartoon: "Bully Boogie", featuring the Boogeyman's first apperance.
Get this movie if you're a fan of the "Grim Adventures" TV series, and also available, the Billy and Mandy videogame for your favorite game console including the new Wii system.
