The moviemaker admits he came up with the idea for the quirky Brad Pitt film after watching 1942 drama Hitler - Dead or Alive.
Tarantino tells Playboy magazine, "A rich guy offers a million-dollar bounty on Hitler's life (and) three gangsters come up with a plan to kill Hitler. They parachute into Berlin (German) and work their way to where Hitler is. It's a wacky movie that goes from being serious to very funny.
"The gangsters get Hitler... they shave his moustache off, cut off that lock of hair and take his s**t off, so he looks like a regular guy. The Nazis show up, and Hitler, who doesn't look like Hitler anymore, is like, 'Hey, it's me!' And they beat the s**t out of him.
"I thought, 'Wow, this is f**king hysterical.'"
