George Orson Welles (May 6, 1915 – October 10, 1985) was an American film director, writer, actor and producer, who worked extensively in film, theatre, television, and radio. Welles was also an accomplished magician, starring in troop variety spectacles in the war years. Noted for his innovative dramatic productions as well as his distinctive voice and personality, Welles is widely acknowledged as one of the most accomplished dramatic artists of the 20th century. His first two films with RKO: Citizen Kane and The Magnificent Ambersons, are widely considered two of the greatest ever made. His other films, including Touch of Evil and Chimes at Midnight, are also considered masterpieces. He was also well-known for a radio adaptation of H. G. Wells' novel The War of the Worlds which, performed in the style of a news broadcast, reportedly caused widespread panic when listeners thought that a real extraterrestrial invasion was in progress.
In 2002 he was voted as the greatest film director of all time in the British Film Institute's poll of Top Ten Directors.Source: Wikipedia
