Béla Tarr, the Hungarian arthouse director best known for his bleak, existential and challenging films, including Sátántangó and Werckmeister Harmonies, has died at the age of 70. The Hungarian Filmmakers’ Association shared a statement on Tuesday announcing Tarr’s passing after a serious illness, but did not specify further details.

Tarr was born in communist-era Hungary in 1955 and made his filmmaking debut in 1979 with Family Nest, the first of nine feature films that would culminate in his 2011 film The Turin Horse. Damnation, released in 1988 at the Berlin International Film Festival, was his first film to draw global acclaim, and launched Tarr from a little-known director of social dramas to a fixture on the international film festival circuit.

Tarr’s reputation for films tinged with misery and hard-heartedness, distinguished by black-and-white cinematography and unusually long sequences, only grew throughout the 1990s and 2000s, particularly after his 1994 film Sátántangó. The epic drama, following a Hungarian village facing the fallout of communism, is best known for its length, clocking in at seven-and-a-half hours.

Based on the novel by Hungarian writer László Krasznahorkai, who won the Nobel Prize in Literature last year and frequently collaborated with Tarr, the film became a touchstone for the “slow cinema” movement, with Tarr joining the ranks of directors such as Andrei Tarkovsky, Chantal Akerman and Theo Angelopoulos. Writer and critic Susan Sontag hailed Sátántangó as “devastating, enthralling for every minute of its seven hours.”

Tarr’s next breakthrough came in 2000 with his film Werckmeister Harmonies, the first of three movies co-directed by his partner, the editor Ágnes Hranitzky. Another loose adaptation of a Krasznahorkai novel, the film depicts the strange arrival of a circus in a small town in Hungary. With only 39 shots making up the film’s two-and-a-half-hour runtime, Tarr’s penchant for long takes was on full display.

Like Sátántangó, it was a major success with both critics and the arthouse crowd. Both films popularized Tarr’s style and drew the admiration of independent directors such as Jim Jarmusch and Gus Van Sant, the latter of which cited Tarr as a direct influence on his films: “They get so much closer to the real rhythms of life that it is like seeing the birth of a new cinema. He is one of the few genuinely visionary filmmakers.”

The actress Tilda Swinton is another admirer of Tarr’s, and starred in the filmmaker’s 2007 film The Man from London. At the premiere, Tarr announced that his next film would be his last. That 2011 film, The Turin Horse, was typically bleak but with an apocalyptic twist, following a man and his daughter as they face the end of the world. The film won the Grand Jury Prize at the Berlin International Film Festival.

After the release of The Turin Horse, Tarr opened an international film program in 2013 called film.factory as part of the Sarajevo Film Academy. He led and taught in the school for four years, inviting various filmmakers and actors to teach workshops and mentor students, including Swinton, Van Sant, Jarmusch, Juliette Binoche and Gael García Bernal.

In the last years of his life, he worked on a number of artistic projects, including an exhibition at a film museum in Amsterdam. He remained politically outspoken throughout his life, condemning the rise of nationalism and criticizing the government of Hungarian leader Viktor Orbán.
