Knockabout is Yuen Biao's outstanding debut film in a starring role, directed by Peking Opera "Dai Gor" (big brother) Sammo Hung. This 1979 action romp is deliciously quirky with some of the best martial arts action of the golden age of Hong Kong cinema. Talk about showcase - Yuen Biao has to be one of the greatest tumblers of all time and he proves it here. An acrobatic prodigy, Yuen Biao (aged 22 at the time) displays inhuman stamina and incredible flexibility, as well as tight, crisp martial arts. And that’s not even mentioning top performances by Sammo, Lau Kar Wing, Brian Leung, Mars and a bevy of recognisable stuntmen. An instant classic, enjoy our summary before or after you watch this - and maybe you can explain to us exactly what Yuen Biao is doing on the movie poster art?!
