Mack Sennett continued to use the Keystone Cops intermittently through the 1920s, but their popularity had waned by the time that sound films arrived. In 1935, director Ralph Staub staged a revival of the Sennett gang for his
Warner Brothers short subject
Keystone Hotel, featuring a re-creation of the Cops clutching at their hats, leaping in the air in surprise, running energetically in any direction, and taking extreme pratfalls. The Staub version of the Keystone Cops became a template for later re-creations.
20th Century Fox's 1939 film
Hollywood Cavalcade had
Buster Keaton in a Keystone chase scene.
Abbott and Costello Meet the Keystone Kops (1955) included a lengthy chase scene, showcasing a group of stuntmen dressed as Sennett's squad. (Two original Keystone Cops in this film were
Heinie Conklin as an elderly studio guard and
Hank Mann as a prop man. Sennett also starred in a cameo appearance as himself).
Richard Lester's ''
A Hard Day's Night'' (1964) has a scene in which
the Beatles are chased around the streets by police in the manner of the Keystone Cops to the tune of "Can't Buy Me Love". In Sydney, Australia, in the 1960s,
Rod Hull,
Desmond Tester and
Penny Spence featured in a local homage series of TV comedy shorts,
Caper Cops. "It’s a direct steal of the American
Keystone Kops [sic], but this is Sydney, Australia, in the late 1960s and who cares..." said creator/star Hull.
Mel Brooks directed a car chase scene in the Keystone Cops' style in his comedy film
Silent Movie (1976).
Canceled cartoon shorts In the late 1960s,
Warner Bros.-Seven Arts was going to create a series of animated cartoon short films based on the Keystone Cops, before being scrapped permanently following the closure of Warner's original animation studio in 1969. == In popular culture ==
