Whether you take [Olivier's] central performance on its own terms (as a 'definitive' reading of the part) or as high camp, it's undoubtedly interesting as a phenomenon.
What are people saying?
What are critics saying?
Donning a doozy of a puttied schnoz, a slightly exaggerated limp, and a boyish, midnight-black wig, Sir Laurence Olivier feels more at home in the eponymous role of his own adaptation of Richard III than he does in any of his other storied roles, holding and releasing the succulent prose with unerring confidence and clarity.
The New Yorker by Pauline Kael
As director and star, Olivier succeeds with the soliloquies as neither he nor anyone else ever did on film before; they're intimate, yet brazen.
Laurence Olivier gives the textbook course on Shakespearean villainy as crown-stealing schemer Richard. Considered by many to be Olivier's best take on the Bard. [22 Feb 2004]
The New York Times by Vincent Canby
Of all Olivier's Shakespearean films, Richard III is, to my way of thinking, the most satisfying, the most surprising and - it has to be said - the funniest. [24 Apr 1981, p.C6]
