Mary Harron’s adaptation of the Bret Easton Ellis novel was instantly controversial but instantly iconic. Robert Donat plays a man who gets caught up in an espionage caper when a strange woman ends up dead in his apartment, and he’s the main suspect. Oscar nominee Ramin Bahrani recently called Hitchcock’s 1935 classic “the origin.” Watching it now, you can see not only how it would shape so many future Hitch works but the many thrillers who tried to copy his formula.
