Charismatic old school action star Norman Tsui Siu-Keung has been acting since the early seventies, when he joined the Shaw Brothers studio. Over a 30 year-plus career, Tsui has appeared in numerous classic action and swordplay epics and has effortlessly essayed proud and chivalrous heroes, as well as fierce and lethal bad guys. He first gained attention as an actor at RTV (now called ATV, the second largest television station in Hong Kong) with his role in the TV series "Reincarnated" AKA "Metamorphosis of the Heavenly Silkworm". The central character of Wan Fei-Yeung has become one of his most popular and infamous roles. Though the series had been winning against TVB in the ratings, Tsui was fired halfway through the series and replaced with another actor due to his periodic disappearances and disputes with the producers. He later starred in The Bastard Swordsman (1983), which is a movie adaptation of the story, and was brought in to play the character again at ATV in 1993 when Wan Fei-Yeung was literally resurrected from the dead for "Reincarnated II".

Tsui has showed off his impressive physical prowess in movies like The Loot (1980) and Shaolin Mantis (1978), and made sure his presence was felt as the stoic Japanese champion swordsman Hashimoto in Ching Siu-Tung's Duel to the Death (1983). He was in many of the early New Wave films; he played a madman suspected of murder in Ann Hui's directorial debut The Secret (1979), was placed onto an island of cannibals as Agent #999 in Tsui Hark's We're Going to Eat You (1980) and played the main villain in Patrick Tam's The Sword (1980). After terrorizing Chow Yun-Fat in Tiger on the Beat (1988) and City War (1988), Tsui battled Michelle Yeoh in Wing Chun (1994) and picked up the sword again for What Price Survival (1994). His recent notable film appearances include Inner Senses (2002) and Jiang Hu (2004).

Over the years, Tsui has appeared in countless numbers of movies and TV serials adapted from the novels of Gu Long (as well as Louis Cha, etc), and was reportedly a good friend of the late, great wuxia scribe. This isn't surprising as they had similar interests: alcohol and beautiful women. Tsui reportedly has a reputation of being a swinger and a hard drinker, and can supposedly drink brandy as if it were water. He's been married several times and all of the marriages have ended in divorce. Among his ex-wives is Suet Lei (former ATV starlet in the eighties and younger sister of Michelle Mai Shuet) with whom he has two children. Tsui's movie appearances have decreased in recent years and he's mainly focused on television work in Taiwan, the Mainland, and even the occasional venture to Thailand (where he apparently has a cult following). Even though he's now in his 50s, Tsui shows few signs of slowing down and reportedly still tries to do as many of his own action scenes as possible. (Yinique 2005)
