Tony Leung, the exceptionally talented Director, Producer, and Action Director, and younger brother of Bruce Leung, took the helm of an explosive Shaw Brothers classic with the film Thunder Clap. Starring Robert Mak and Chen Kwan Tai, this action-packed masterpiece became a must-see for Kung Fu fans, especially in the early '80s when it was notoriously difficult to find. In Thunder Clap, Tony Leung plays the role of a legendary human lion fighter, renowned for his exceptional and nearly invincible martial arts skills. Pitting his character against various clans, the film delivers some of the most intense, jaw-dropping action ever seen in a Shaw Brothers production.

The action choreography in Thunder Clap stands out as some of the best the Shaw Brothers ever produced, setting a new standard for martial arts cinema.

Tony Leung's innovative direction and ability to craft unforgettable characters make Thunder Clap a definitive entry in Shaw Brothers history—a film every true Kung Fu aficionado should experience.
