14-year old Yagira Yuya was the surprise winner of the Best Actor award at the 57th Cannes Film Festival on Saturday night. Yagira was recognized for his performance in “Daremo Shiranai” (Nobody Knows), loosely based on a true story from the 1980s of four siblings abandoned by their mother. Visually striking, it was criticized as overlong by some reviewers. It was directed by Koreeda Hirokazu, who accepted the award on his star’s behalf. Yagira left Cannes on May 13 after the movie was screened, to go back to mid-term exams at school. He is the first Japanese to win the best actor award at Cannes, and stole the limelight from some more established Japanese stars trying to make an impression at the festival.
