 As a child , Mark Hartley discovered many of the " Ozploitation " B @-@ movies from the 1970s and ' 80s while watching late @-@ night television , but was disappointed when they were completely overlooked in books he read detailing Australian cinema . After becoming an accomplished music video director , his interest in this era of Australian filmmaking grew and he spent years researching a potential documentary film . He was close to giving up on the project when he sent a 100 @-@ page draft of the script to American film director Quentin Tarantino , not expecting to receive a reply . Tarantino was a longtime fan of " Ozploitation " films and had even dedicated his film Kill Bill to Brian Trenchard @-@ Smith 's work . He replied the day after , telling Hartley that he would do whatever he could to get the film made . Hartley traveled to Los Angeles , California to meet with Tarantino , who agreed to sit for hours of interviews as one of the film 's most prominent <unk> . Hartley spent the following five years interviewing other actors , directors , screenwriters and producers , collecting original stock footage , and then cutting the 100 hours of interviews and 150 hours of film footage down into a 100 @-@ minute film .
