Dean Riesner

Dean Riesner (November 3, 1918, New Rochelle, New York – August 18, 2002, Encino, California) was an American film and television writer.

Riesner's father, Charles Reisner, was a German American silent film director, and Dean began acting in films at the age of five as "Dinky Dean". His most notable role was in Charlie Chaplin's 1923 film The Pilgrim. His career at this young age ended because his mother wanted her son to have a real childhood. As an adult, his first job in films was as a co-writer of the 1939 Ronald Reagan movie Code of the Secret Service.

Riesner won an Oscar for directing Bill and Coo (1948), a feature film with a cast of real birds, costumed as humans, acting on the world's smallest film set.
