If There Is One Comedy Actor,

that stands head and shoulders above all others,

it has got to be in My opinion Buster Keaton, widely celebrated for doing many of His own stunts, a long lost one had come to light,

it is a take on the old myth that if You dig a hole You will end up in China,

in this clip from His film Hard Luck He does just that, falling through to China to return a few years later with His Chinese family, the film was lost for many years until it was partially reconstructed in 1987- without the pool scene, that part was finally found in a Russian archive years later and here it is above, 

here is the full film made in 1921, or if you want just to see some of His amazing stunts and funnies,

 this short compilation is for You, what a truly talented comedy actor.
