The Amazing Screw-on Head is the title of a one shot comic book written and drawn by Mike Mignola of Hellboy fame. The comic was published by Dark Horse Comics in 2002, and an animated pilot was made by the Sci-Fi Channel in 2006. It may yet become a series, based on the feedback from a now closed viewer survey.While similar in tone and theme to Hellboy, The Amazing Screw-On Head is a steampunk comedy.
The voice cast is great with Paul Giamatti as Screw-on head, and David Hyde Pierce as Emperor Zombie, the highly intelligent and articulate power mad zombie villain. Aided by Mr. Groin (a butler) and Mr. Dog (a stuffed dog) Screw-on head fights the occult and supernatural threats as an agent of Abraham Lincoln.
