In 2001, Slim moved into film with the establishment of Umam Productions, which has produced several films, including Massaker[5] co-directed by Slim and winner of the Fipresci Award at the Berlin International Film Festival in 2005.[6] In 2004, he co-founded Umam Documentation & Research (D&R), a non-profit organization based in the southern Beirut suburb of Haret Hreik, where the organization is creating an open archive of materials concerning Lebanon's social and political history. The organization organizes and facilitates exhibits at its famous “Hangar”[7] for artists to openly address the scars of the Lebanese Civil War (1975–1990), which is considered taboo and taught neither at the elementary or high school levels.
