Charlie Chaplins fourth film for Mutual is a tour de force solo performance, with Chaplin playing his classic drunk, returning home in the wee hours. The only other character in the film is the taxi driver who is oblivious to Charlies difficulties getting out of the cab. Charlie has equal problems getting into his house. He cant find his key and enters via a window, but he soon finds his key in his vest pocket and exits via the window, reentering in the proper way, through the door. His house is filled with inanimate objects, which to his mind, are ganging up against him. The stuffed animals seem to attack him as he slides on throw rugs along the slippery floor and tries to reach a liquor bottle on a revolving table that keeps eluding him. When he attempts to climb the stairs, he is repeatedly struck by the oversized pendulum of a wall clock and sent tumbling down the staircase. Finally reaching his bedroom, his automatic Murphy bed seems to have a mind of its own, trapping him as it revolves round and round inside its wall compartment, bucking him like a bronco when he sits on it and falling on top of him when he lays on the floor. Finally abandoning the bedroom, Charlie goes to the bathroom, soaking himself as he tries to get a drink from the shower stall and then settling down for the night in the bathtub. Although essentially plotless, One A.M. is a brilliant clinic in physical comedy and the psychology of alcoholic delusions. ~ Phil Posner, All Movie Guide
