In the early 1980s, Jackie Chan began experimenting with elaborate stunt action sequences in films such as "The Young Master" (1980) and especially "Dragon Lord" (1982), which featured a pyramid fight scene that holds the record for the most takes required for a single scene, with 2900 takes, and the final fight scene where he performs various stunts, including one where he does a backflip off a loft and falls to the lower ground. In 1983, "Project A" saw the official formation of the Jackie Chan Stunt Team and added elaborate, dangerous stunts to the fights and typical slapstick humor; at one point, Chan falls from the top of a clock tower through a series of fabric canopies. Critics have compared his comedic stunts in "Project A" to Buster Keaton, who was also known to perform his own stunts, although Chan himself had not watched Keaton's films until years after "Project A" released; according to Chan, "Project A" was an evolution of the action stunt work he had been doing in earlier kung fu comedy films since "The Young Master".
