The Tokyo restaurant sequence alone must have taken a week to edit.
Spoiler alert: A lot of people die in Quentin Tarantino movies.
You're probably thinking, "Yeah, I know that. I've seen those movies," but I suspect that your memory is failing you when it comes to just how many people die in these films. I can't back this up with neurological data or anything, but I suspect that the human mind can only hold the memory of so many heads being severed in geysers of blood and torsos being blown apart by impossibly forceful hand cannons. Like an evolutionary adaptation to keep us from going insane in times of war or Italian horror movie marathons.
It turns out that if you took all the death scenes—just the seconds-long fragments of character expiration—and strung them all together, the stream of cinematic oblivion would last about four-minutes and twenty seconds. And furthermore, if you played The Delfonics’s "Didn’t I Blow Your Mind This Time" over the whole thing, it would be somewhat beautiful.
