Although Welles is mostly commended for his brilliant directing job in this masterpiece, his performance also ranks among one of the greatest of all-time. At the age of 25, Orson Welles manages to believably portray a man who ages from 25 to 70 throughout the course of the film. He masters the part physically, portraying gradually increasing fatigue to the point that when he tears apart his wife’s room at the end, it comes as no easy task. He matches the physicality with great emotional depth as we see his ego begin to control him.
