Holy shit, it's the exact same speech Sam Jackson said, except they replaced "the Lord" with Sonny Chiba's name in the movie (fair enough). Although it's conveyed through a Star Wars-like text crawl instead of a Jacksonian shout, the menacing inflection of the guy reading the text is pretty much the same.
Whoever wrote that tagline poets the balls out of Tarantino.
This intro is only present in the English version of the film, which is the one Tarantino saw. Presumably he also saw the '80s TV series Shadow Warriors, where Sonny Chiba's character has a habit of lecturing his enemies about good and evil before killing them, just like Sam Jackson's hit man character in Pulp Fiction.
So the question is: Why didn't Tarantino just cast Sonny Chiba? He actually did ... in Kill Bill, as sword-maker Hattori Hanzo.
Who had grown up and decided sushi was much cooler than killing people.
