What is the largest amount of fake blood ever used in a movie?

Answer 1

I'm not sure but that scene in The Shining where rivers of blood pour into, and flow down, a passageway must go close.

You will see it here, at 4 mins and 5 secs mark:

And here 1 min and 30 secs in:

That's probably right for the single most use of fake blood in a film (like in one go), but if you really want an absolute squirting bloodfest of film i suggest you watch Tokyo Gore Police- it's ridiculously awesome, trust me haha

Answer 2

An estimated 500 plus gallons of fake blood was used in the original film.
