Martial art film standout Liang Chia-jen brings the same animalistic intensity from his early heroic bloodshed films to his Danger Has Two Faces tough, ex-cop character now relegated to becoming a pet store owner. The stern Police Superintendent Liu played by Chu Chiang sets the stage for his later role in John Woo's The Killer while new comer Fei Hsiang must do Serpico-like things to find out which cop is paid for by the mob.
