Olivier played Othello in blackface. He also adopted an exotic accent of his own invention, developed a special walk, and learned how to speak in a voice considerably deeper than his normal one. Columnist Inez Robb disparagingly compared Olivier's performance to Al Jolson in "The Jazz Singer". She described Olivier's performance as "high camp", and said "I was certainly in tune with the gentleman sitting next to me who kept asking 'When does he sing "Mammy"?" Film critic Pauline Kael gave the production and Olivier's portrayal one of her most glowing reviews, shaming the major movie studios for giving Olivier so little money to make the film that he and the public had to be content with what was almost literally a filmed stage production, while other films received multimillion dollar budgets. John Simon, while disagreeing with the approach the production's interpretation took, declared that, "Olivier plays this misconceived Othello spectacularly, in a manner that is always a perverse joy to behold".
