Theatrical Release Information:
The Amazing Screw-On Head

An artifact that will allow anyone who possesses it to threaten all life on Earth has been stolen by the most dangerous criminal known to man, and now it's up to President Abraham Lincoln's top spy - a disembodied head known only as The Screw-On Head - to retrieve it in Hellboy creator Mike Mignola's hilarious send-up of Lovecraftian horror and steampunk insanity. The dreaded Emperor Zombie (David Hyde Pierce) is threatening to unleash the greatest horror that mankind has ever known, and the only one who can stop him is Screw-On Head (Paul Giamatti). Now, with time running out for all of humanity, Screw-On Head enlists the aid of loyal manservant Mr. Groin and talking canine Mr. Dog in retrieving the priceless artifact and saving the world from a grim and violent fate. As the ultimate confrontation draws near, Screw-On Head searches high and low for a body powerful enough to fight and overcome the horrible powers that have been unleashed by Emperor Zombie. ~ Jason Buchanan, All Movie Guide
