The drama "The Woman Who Left" ("Ang Babaeng Humayo") by Lav Diaz of the Philippines has won the Golden Lion for best film Saturday at the 2016 Venice International Film Festival.
The almost four-hour film, shot in black and white, tells the story of a defendant wrongly convicted and imprisoned for 30 years, who then struggles to recover her life.
Some 20 films competed for the top prize this year.
The head of the nine-member jury was British director Sam Mendes.
Earlier Saturday, Germany's Paula Beer won the Marcello Mastroianni Award for best emerging actor for her role in "Frantz" by Francois Ozon.
In the drama, Beer plays a young woman who meets a French soldier while she is mourning the death of her fiance after World War I.
Beer won the award for her quiet and nuanced portrayal, according to the judges.
The Venice Film Festival is the oldest in the world.
