With The Water Nymph (aka The Beach Flirt) — the very first Keystone Comedy — begins an era of dominance in movie slapstick by Mack Sennett and his repertory players.
Those who either received their first break in the movie business at Keystone, or rose to prominence therein, include Charlie Chaplin, Mabel Normand, Fatty Arbuckle, Harold Lloyd, Ford Sterling, Gloria Swanson, Ben Turpin, Harry Langdon, and Chester Conklin. And, of course, there’s the Sennett Bathing Beauties.
P.S. If anyone can find a higher quality version of this film, please let me know.
