Lam was born in Tianjin, and came to Hong Kong as a youth in 1979 to receive inheritance money left by his grandfather. Soon after all the money had been squandered and Lam had to work various odd jobs to make a living. In the mid-eighties he got employment on movie sets through the help of friends. He has done different roles, from lighting and props to stage manager and set and script supervisor. Lam gradually developed an interest in acting and by his own account, pestered various directors until they relented and gave him tiny roles. There are two pivotal persons in Lams acting career. The first is Stephen Chow, who befriended him in his early days as a crew member and cast him in movies like The God of Cookery (1996) and Kung Fu Hustle. The second person is director Johnnie To. Lam has been in over 80 films since 1996 and at least 20 of those have been directed or produced by To. Known for his weight and size, his roles are often as a bumbling secondary character providing comic relief from the most intense nature of Tos films. He is perhaps most famous for his various supporting roles in Tos films, notably as the bumbling taxi driver Yip in the award winning film Breaking News (2004). The most notable To-Lam collaborations include The Mission, which garnered Lam Best Supporting Actor nominations at the Hong Kong Film Awards and the Golden Horse Award, and PTU.
