Born Yin Ying Lo in Guangdong, China, Helena began acting as a teenager in the early 1950s and took the stage name Law Lan after actress Sophia Loren ("Law Lan" being the Cantonese pronunciation of Loren's last name). She would go on to become one of the most prolific actresses in the world, amassing well over 500 film and TV acting credits to date. Though she's adaptable to any genre, in later years she carved a niche out for herself in horror films, including the seemingly-endless Troublesome Night series.
