Quentin Tarantino was originally going to play Mr Pink, although he made a point of letting all the other actors audition for the part. When Steve Buscemi came in to read for it, Tarantino told him that he really wanted the part for himself and that the only way Buscemi could possibly wrest it from him was to do a killer audition. Buscemi duly complied.
