In Russia, the film was renamed. That's okay, they couldn't translate this pun. Why in the hell they called it ''A Zombie Named Shaun' is beyond me, particularly because Shaun doesn't become a zombie!
In Spain, the film was inexplicably released as "Zombies Party" (in English). To make it worse, the subtitle "A romantic comedy... with zombies" was changed to the very lame "A night... of death". Even though most of the film takes place during the day.
Disabled Character, Disabled Actor: Amputees were used for several of the zombies, most notably a one-armed bridegroom, and a legless zombie Shaun and Ed accidentally run over.
I Want You to Meet an Old Friend of Mine: When Shaun, Liz, David, Dianne, Barbara, and Ed run into the alternative "gang" as they make their way to the Winchester, there are quite a few comedy partnerships brought together again.
Promoted Fanboy: Many of the zombie extras are fans of Spaced. They were recruited through the Spaced Out fan website to be in the film.
Real-Life Relative: Lucy Davis encouraged her mom Hazel to turn out as a Zombie extra. You have to look swiftly and know exactly where, but you can spot Hazel. Hazel is perhaps better known for her lifelong marriage to comedic legend Jasper Carrott.
Stillborn Franchise: Pegg and Wright considered a sequel that would replace zombies with another monster, but decided against it as they were pleased with the first film as a stand-alone product, and thought too many characters died to continue the story.
The title? From Dusk Till Shaun.
Unintentional Period Piece: A large factor in deciding to hide out at the Winchester is that Ed will be allowed to smoke. This immediately dates the film, since while it was legal to smoke in enclosed public places (such as pubs) in England in 2004, when the film was made, it's been illegal since 2007.
What Could Have Been: The original script called for Shaun to beat Mary and the hulking zombie with a girl's bicycle.
