The conception of '' The Black Power Mixtape 1967-1975 '' is unique in that the 16 mm film footage used was originally shot by Swedish journalists in the 1960s and 1970s for Swedish Television , but the editing and release of the film did not take place for more than 3 decades after the era when it was discovered by director Göran Olsson . The setting of the footage featured in the documentary spans across the US and Europe and includes shots in Harlem , Oakland , and Brooklyn . Although Swedish journalists conducted the interviews , the film was co-produced by Americans Joslyn Barnes and actor Danny Glover through their independent film production company , Louverture Films . The production company is geared toward producing " independent films of historical relevance , social purpose , commercial value and artistic integrity " . '' The Black Power Mixtape 1967-1975 '' was screened at both the 2011 Sundance Film Festival and the 61st Berlin International Film Festival . The rights of the documentary were later acquired by Sundance Selects , a sister label to IFC Films . The documentary was also featured on a February 2012 episode of PBS 's '' Independent Lens ''
