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.
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.
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.
