William P. Carlton on AllMovie

A tall, distinguished-looking actor from England, William P. Carleton played Lieutenant. Hardy in the screen version of The Cobberhead (1920), a role he had originally essayed on Broadway. Often cast as the "other man" or stern government officials, Carleton would on occasion play the romantic lead, such as his role opposite Clara Kimball Young in the still extant The Worldly Madonna (1922). A bit player in the sound era, the veteran actor ended his screen career playing supporting roles in a couple of serials: The Adventures of Captain Merriwell (1936) and The Green Hornet Strikes Again (1940). He died from injuries sustained in a car accident.
