Document 7: List of accolades received by The Act of Killing: "The Act of Killing" (Indonesian: "Jagal" ) is a 2012 Danish-British-Norwegian documentary film directed by Joshua Oppenheimer, Christine Cynn, and an anonymous Indonesian co-director. The film explores the social significance of the Indonesian mass killings of 1965–1966 by focusing on the perpetrators and having them produce reenactments of the killings in the style of various Hollywood genres. The film's primary subjects had been petty criminals, but came to lead a powerful death squad during the anti-communist purge which resulted in the death of an estimated 500,000–2,000,000 suspected communists, communist sympathisers, alleged leftists, and ethnic Chinese. As many of the institutions and people responsible remained in power, those who carried out the killings were never held to account and continue to hold positions of power and respect. Oppenheimer was struck by the extent to which people not only rationalised but boasted about their participation in the killings, and used the film to explore the role the events continue to play in people's lives in the present. According to Oppenheimer, it is "about a regime in which genocide has, paradoxically, been effaced and celebrated – in order to keep the survivors terrified, the public brainwashed, and the perpetrators able to live with themselves."

Document 12: Killswitch (film): Killswitch is a documentary film about the battle for control over the Internet. The movie is a collaboration between director Ali Akbarzadeh, producer Jeffrey Horn, writer Christopher Dollar and Akorn Entertainment. It premiered at the Woodstock Film Festival in October 2014, where it won the James K. Lyons Award for Best Editing of a feature documentary and then made its international debut, playing alongside "Citizenfour" at the International Documentary Film Festival Amsterdam in November 2014. In 2015, it screened on Capitol Hill, as well as film festivals on four continents (Europe, Asia, Australia, and North America). The tech world has been excited by democratic presidential candidate Lawrence Lessig's role in the film. Kathy Gill of GeekWire writes that ""Killswitch" is much more than a dry recitation of technical history. Director Ali Akbarzadeh, producer Jeff Horn, and writer Christopher Dollar created a human centered story. A large part of that connection comes from Lessig and his relationship with Swartz." Since Killswitch's recent release to a popular audience on Netflix, critics have hailed the film as one of the best documentary films to watch in 2017.
Document 13: Roy Andersson: Roy Arne Lennart Andersson (born 31 March 1943) is an acclaimed Swedish film director, best known for "A Swedish Love Story" (1970) and his "Living trilogy," which includes "Songs from the Second Floor" (2000), "You, the Living" (2007) and "A Pigeon Sat on a Branch Reflecting on Existence" (2014). "Songs from the Second Floor", more than any other, cemented and exemplified his personal style – which is characterized by long takes, absurdist comedy, stiff caricaturing of Swedish culture and Felliniesque grotesque. He has spent much of his professional life working on advertisement spots, directing over 400 commercials and two short films, but only directing six feature-length films in six decades. His 2014 film "A Pigeon Sat on a Branch Reflecting on Existence" won the Golden Lion award at 71st Venice International Film Festival, making Andersson the only Swedish director and the second Scandinavian director to win the award in the history of the festival, after Danish Carl Theodor Dreyer won in 1955. Anderson is considered one of the most important living European film directors, having four films officially submitted for the Academy Award for Best Foreign Language Film as Swedish entries.
