Corrected entry: Braindead has been recorded as the bloodiest film ever, literally. About 600 gallons of fake blood was used during the production.
Corrected entry: When the zombies pop out of the basement floor, doesn't it look like a really bad KISS show? Especialy when the thug zombie pops out.
Correction: This hardly qualifies as trivia.
Correction: There is one film having more fake blood ("Nightmare on friday the 13.", with ca 1200L blood).
