Joshua Oppenheimer’s follow-up to his Oscar-nominated documentary The Act of Killing will have its world premiere screening in competition at this year’s Venice International Film Festival.

The Look Of Silence (pictured) is a companion piece to Killing, which focuses on the family of a genocide survivor in Indonesia who confront the man who killed one of their brothers. The film is one of a handful of docs screening at the 71st annual event, which runs from August 27 to September 6.

Documentaries screening in the out-of-competition program include Austrian director Ulrich Seidl’s In The Basement, Gabriele Salvatores’ Italy In A Day, and Davide Ferrario’s La Zuppa del Demonio.

Io Sto Con La Sposa, from directors Antonio Augugliaro, Gabriele del Grande and Khaled Soliman Al Nassiry will screen as part of the festival’s international competition.

Meanwhile, Ron Mann’s long-awaited Altman documentary, about the legendary American director, has been selected to screen out of competition in the Venice Classics sidebar, where Mann will also be on the festival jury for best debut film.

The film is the Canadian director’s ninth documentary and chronicles the life of the late Robert Altman, best known for classic movies such as M*A*S*H, McCabe & Mrs. Miller, Nashville, The Player and Gosford Park.

The film marks Mann’s debut appearance at Venice and was made with the cooperation of Altman’s wife, Kathryn Reed Altman. It has already been shown in June at the Hammer Museum in Los Angeles. Altman will also screen on August 1 at the TIFF Bell Lightbox in Toronto and is set to be released in Canadian theaters this fall by Films We Like.

As previously reported, Spanish director Alex de la Iglesia’s docudrama portrait of Argentinian soccer player Lionel Messi will close in the festival’s Venice Days sidebar program.
