Orson Welles was a renowned actor, director, writer and producer best known for his 1941 film Citizen Kane. At age 23, Welles caused a panic with his realistic radio dramatization of The War of the Worlds. He was later offered complete artistic control by RKO to make Citizen Kane, his first film. Citizen Kane was groundbreaking for its technical innovations including lighting, camerawork and storytelling techniques. Though it is now considered one of the greatest films ever made, it was a financial failure upon release due to controversy surrounding its unfavorable portrayal of newspaper magnate William Randolph Hearst, on whom the main character was loosely based.
