James Robertson Justice (15 June 1907 - 2 July 1975 ) was a popular English character actor in British films of the 1940s, 1950s and 1960s.

James Robertson Justice was always a noticeable presence in a film with his large stature, bushy beard and booming voice. A Ph.D., a journalist, a naturalist, an expert falconer, a racing car driver, JRJ was certainly a man of many talents. He entered the film industry quite late in life (37) after he was spotted serving as MC for a local music hall. He became a familiar figure on-screen after a succession of "larger than life" roles during the 40s and 50s, and particularly as Sir Lancelot Spratt in the "Doctor" film series.
