Stephen Tung Wai (Chinese: 董瑋; born 2 February 1954) is a Hong Kong action choreographer, actor, and film director.

[3][4] Due to their family's financial situation, his grandfather sent him to learn wing chun and practice Cantonese opera with actress Fen Juhua, instead of going to school.

[1][4] Tung was only enrolled in primary school at the age of eleven, upon his aunt's request, but his grandfather withdrew him after the third year to support their livelihood.

[5] Tung starred in the war film Squadron 77 as a child actor in 1965 and began working as a stunt double when he was sixteen.

[5][6] In 1986, Tung served as the action choreographer for John Woo's A Better Tomorrow and Tsui Hark's Peking Opera Blues.

[11][8] Tung admitted that he did not enjoy directing as he struggled with interpersonal relationships and chose to remain focused on action choreography.

[10][12] In 1994, Tung choreographed and executive produced the drama film The True Hero [zh], for which he received a nomination for Best Action Choreography in the 31st Golden Horse Awards.

[18] In 2003, Tung went to Hollywood and choreographed the American action comedy film Bulletproof Monk, directed by Paul Hunter.

[22] However, he found the Western filming environment to be too industrialized and lacking in creative freedom, and he preferred working within Hong Kong action cinema.

[10] In 2005, Tung assumed the role of action choreographer in Tsui Hark's Chinese-Hong Kong wuxia film Seven Swords.

[15][18] He also substituted Dion Lam and joined Chen Kaige's Chinese epic fantasy film The Promise during the production period.

[49] He invited Japanese action choreographer Kenji Tanigaki, who was working as a cast extra, to join the Association and enter the stunt industry in 1994.

[50][51] He also discovered British actor Scott Adkins and cast him in the 2001 action film Extreme Challenge, which marked the beginning of his acting career.
