This one is mentioned here because of the sheer physicality of the role of the tramp in this film. With the machine scene and the skating, what he performs here is utterly amazing. This type of stuff would not be done with a live person today as he did it then, but with CGI.
Charlie Chaplin had taken to the roller skates before in 1916’s The Rink, but his crowning moment on the little wheels came in this classic. He and Paulette Goddard don the skates in the fourth floor toy room of a department store and he glides around ever-so-gracefully, blindfolded, right next to a precipice, while gorgeous gamin’ Goddard stumbles around trying to warn him. It’s classic. And still hair-raising! The effect, however, was created using a matte, so there was actually no huge drop and no risk to the actor. His blindfold, meanwhile, was a see-through mesh. But he did all the skating himself — devoting a whopping eight days to the short scene.
Modern Times was directed by Charlie Chaplin for Charles Chaplin Productions.
