English: The Keystone Cops in a typical pose : Scene from In the Clutches of the Gang (1914) directed by George Nichols and Mack Sennett. The desk officer using the telephone is Ford Sterling. The policeman directly behind Sterling (in extreme background, left) is Edgar Kennedy. Next to Kennedy is an unknown William Frawley aged 27. The hefty policeman at extreme right is Roscoe "Fatty" Arbuckle. The young constable with bulging eyes, fourth from right, is Arbuckle's nephew Al St. John. The casting of the Keystone police force changed from one film to the next; many of the individual members were per-diem actors who remain unidentifiable.
