Donnie Yen is a Hong Kong actor, filmmaker, martial artist, and action director.
When he was two years old, his family moved to Hong Kong and then to the United States when he was 11, settling in Boston. He attended Newton North High School.
At a young age, under the influence of his mother, Yen developed an interest in martial arts and began experimenting with various styles, including tai chi and other traditional Chinese martial arts. At age 16, Yen began practising Wushu after his parents sent him to Beijing to train with the Beijing Wushu Team.
At age 18, when Yen was returning to the United States to visit his family, he made a stop in Hong Kong, where he met and auditioned for action choreographer Yuen Woo-ping.
