Alexander Lo won the Taiwan 1978 Tae Kwan do championship, and got into the movie business after his older brother Tong Lung introduced him to director Robert Tai, with whom he most frequently collaborated. Alexander worked on many films about Ninjas, such as Ninja Insan avcısı (1987), Süper Ninja (1984), Shao Lin tong zi gong (1983), Ninjas, Condors 13 (1987), and Kara Cellat (1985). He also worked on Shaolin films such as Shao Lin tong zi gong (1981) and the famous Shao Lin dou La Ma (1983). In 1984, Tai directed Lou in a nine-hour epic titled Ren zhe da (1986), and some time after this epic film, Alexander quit acting but did not stop making movies. He continued a long partnership with Robert Tai, only this time as an action choreographer, working on such films as Jing wu ying xiong 2: Tie bao biao (1996). He often collaborated with his good friend, the African-American kick-boxer Eugene Thomas (Trammell), where they either fought together as a black/Asian duo, or faced up against each other as arch enemies.
