After 8 years, Dead Alive is still champion of using the most
fake blood in any movie.
Over 1,000 gallons of fake blood, consisting of chocolate syrup and water, was used for the movie. Only half of the fake blood was using during the zombie kung-fu scenes and the lawn mower vs. zombies fight. The rest was used in the last scene, when the giant zombie mother bursts. Yuck.
Some movies in the same slap-stick horror genre: Evil Dead, Evil Dead 2, Army of Darkness
