William Pitt Striker Earle (December 28, 1882 – November 30, 1972) was an American director of the silent film era. He attended Columbia University and worked for a time as a photographer before breaking into the movie business by sneaking onto the lot of Vitagraph Company of America to observe how directors worked. After a few days of this, Earle approached the studio president and was given his first movie to direct, For the Honor of the Crew, a short about a crew race at Columbia University. He subsequently directed a number of features and shorts for Vitagraph. Later he worked with producer David O. Selznick. Earle founded his own, short-lived production company called Amex Production Corporation with J. S. Joffe, and shot the final two films of his career in Mexico.
