Quentin Tarantino has linked filming Uma Thurman's fight to climbing Mount Everest.
The filmmaker has revealed to Britain's Culture magazine that making the two "Kill Bill" films were a couple of the hardest in his life - and compared it to trekking up the world's tallest peak.
Tarantino said, "I consider making 'Kill Bill' as like me climbing Mount Everest. I taught myself how to climb as I climbed it. I would write all these scenarios of things that could happen with Uma Thurman's character and then I would think, 'Nah, I don't want to go there.'"
The energetic director, who found fame with "Reservoir Dogs" and "Pulp Fiction," revealed sequences he considered adding to the film.
He said, "I wanted her to get into a big car chase. She's in the Pussy Wagon and drives under the 'bat bridge' and there are bats bouncing off the windshield. You cut to the outside of the bridge, and it's like two million bats and this car - BOOM!"
Since the widely popular "Kill Bill" movies were released, Tarantino has laid low, doing small work on features such as "Sin City." However, he does have a new film in the works and is currently mentally preparing for another climb.
He said, "Now that I've climbed Mount Everest I don't know if these little hills are going to be so attractive. I don't know if I want to start that expedition again. I've been planning this war film for a while and its time to do it. But it's a big, Mount Everest kind of epic, and I've already climbed it, so I've got to get myself to do it again."
