I don’t want to give you a wrong number, but — did you say 7,000? Multiply by ten. It was somewhere around 80,000 [gallons]. We were using very dense blood and we had to put that in the water. The amount of blood we had to pour in the lake was around that number.It may be the most blood ever used, and it is violent and graphic somehow, but it’s never, I hope, disgusting or over-the-top. I didn’t make this movie to use that much blood. Because 20,000 kids getting attacked at spring break is a lot of blood in the water. I just respect the medical rules: one gallon equals one person. — Vulture with a vitally important Q&A.
