Born April 22, 1955, in Hong Kong, To served as an assistant TV director before helming his first feature film, the 1980 martial arts fantasy The Enigmatic Case. Audiences quickly became addicted to the blend of masculinity and male bonding he offered in movies such as The Big Heat (1988) and All About Ah-Long (starring Yun-Fat Chow).
After forming his own production company in the '90s, To returned to directing with a series of films focusing on characters and action, including The Mission (1999), Fulltime Killer (2001) and 2005's Election (which was nominated for a Golden Palm at the Cannes Film Festival).
Top assassin "O" finds his status challenged by Tok, a mysterious man whose reckless style of killing has made him the latest darling in the world of hit men. While duking it out for the top spot, both men must evade a determined Interpol inspector.
