The critically acclaimed film Bi, Dung so (Bi, Don't be afraid) won the Best First Feature and Best Cinematography awards at the Stockholm Film Festival Saturday night.
The film's director Phan Dang Di beat the directors of My Joy, a nomination at Cannes, and Winter's Bone, a winner at Sundance Festival, US for the Best First Feature award.
The award is given to a director with only one or two films under his belt.
Bi, Dung so unfolds the story of people struggling to escape from loneliness.
It tells the story of 6-year-old Bi who lives with his parents, aunt and a maid in an old house in Hanoi, and the relationship he develops with his paralyzed grandfather.
Di has captured abundant glimpses of characters who are revealed through behavior rather than conventional plot.
Pham Quang Minh, the cameraman of the film, won an award "for poetic and dignified simplicity and subtle technical perfection," said judges.
Holly Hunter, the leading judge, said she really likes Bi, Dung so, praising the scenes and performances of the actors.
The film has attended more than 30 international film festivals in the past year. Most recently at the Hong Kong Asian Film Festival on November 8, it was named the best film in the New Talent category, an award for new filmmakers.
Earlier at this year's Cannes film festival, it won two Critics' Week awards including the best screenplay.
The film's director also won a special mention among young Asian directors at the Vancouver International Film Festival in October.
Di's film is expected to be in Vietnamese cinemas soon. It is going to be screened on Arte, a Franco-German TV network which describes itself as a European culture channel.
Launched in 1990, the Stockholm International Film Festival is held annually in Stockholm, Sweden.
The best films win the Bronze Horse awards. The 21st edition of the festival gave three horses including one for best film to Winter's Bone by Debra Granik.
