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 and Jenny "The Bloggess" Lawson). 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.
Animating the cheesy horror film that Norman is watching at the start of the movie was reportedly very difficult for the film makers, as they had to intentionally make a bad film (bad camera angles, poor focus, bad "acting" etc) while still working in the very technically demanding confines of stop motion animation
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.
Jeff Garlin's 4th Theatrically Released Animated Film, after WALL·E (2008), Toy Story 3 (2010), and Cars 2 (2011), as well as Garlin's first Animated Film to not be from Disney/Pixar, and his first animated film to be Rated PG by the MPAA.
After the angry mob comes to terms with the zombies, Norman asks to borrow his fathers car. Norman and his father are driving down the street past a neon sign that says 'witchy wieners' - the 'w' in witchy flickers out leaving a humourous result.
