The irrepressible, stonefaced Buster Keaton is always a welcome guest on the Brattle’s screen—and even more so on this day meant to celebrate the glory of silent cinema! In COPS, a 1922 ‘two-reeler,’ Buster plays his usual hapless everyman who, through a series of accidents and mistaken identities, finds himself chased all over town by every cop on the force. Screening with Keaton’s THE ELECTRIC HOUSE (1922), THE BLACKSMITH (1922), and THE GOAT (1921).
