During the last few weeks leading up to the film's release, Laika sent 49 packages to 49 people (including Neil Gaiman and Kevin Smith). Each package consisted of a wooden crate from "Blithe Hollow" full of "grave dirt" which recipients had to dig through to unearth a coffin. Inside the coffin was one of the seven cursed zombies, complete with background information and name.
The film was shot using a Canon 5D Mark II DSLR Camera. To generate the 3D effects, the camera was mounted on a special rig that would take one shot, then slide to a slightly different viewpoint to take another shot.
Save for Judge Hopkins, the seven cursed zombies are not referred to by name, but they did have names: the aforementioned Judge Hopkins, Eben Hardwick, Thaddeus Blackton, Lemuel Spalding, Amelia Wilcot, Goodie Temper, and Wile London.
