Samuel L. Jackson had been in over thirty films before Pulp Fiction (and had even won a special jury prize at Cannes) but when this movie hit he became a cultural phenomenon. While rooted a bit in 70s blaxploitation, his badass persona as the wisecrackin' tough guy became beloved by pretty much any dude who ever drank a can of beer.
Kangol hats became fashion statements. Even Nick Fury, a comic book character, was redrawn to look like him. With Snakes on a Plane, fans were saying his dialogue before it was even written. He is the highest grossing live action movie star in Hollywood. Indeed, a Badass MFer.
