The Boondock Saints director Troy Duffy gleefully admits that he ripped off Quentin Tarantino for the Willem Dafoe scenes. Written and directed by Duffy in his feature debut, the 1999 film follows Irish twin brothers who turn into vigilantes after killing two Russian mobsters in self-defense and, following a shared epiphany, the brothers embark on a mission to cleanse Boston of its criminal underworld in the name of God, all while being tracked by an FBI Agent. The movie stars Willem Dafoe, Sean Patrick Flanery, Norman Reedus, David Della Rocco, and Billy Connolly.
