Jackie Chan’s film career began in the early 1970s, where he initially worked as a stuntman in Bruce Lee films such as “Fist of Fury” and “Enter the Dragon.” His big break came with the 1978 film “Snake in the Eagle’s Shadow,” followed by “Drunken Master” in the same year. These films showcased his unique blend of martial arts, comedy, and stunts, which would become his trademark style.
