North by Northwest, directed by the one and only, Alfred Hitchcock stands as one of my favorite suspense thrillers. It features Cary Grant as Roger O. Thornhill, an ad executive who finds himself chased by a sinister organization because they mistake him for a spy.
This film has it all...Amazing composition, Saul Bass opening titles, a riveting Bernard Hermann score, the climb and big finale on Mount Rushmore, and of course, who can forget the famous crop duster scene??! A lesser filmmaker would have kept the film dark and moody but Hitchcock wisely keeps it light and even comedic at times without loosing the suspense and thrill of the chase.
Also worthy of note is Cary Grant's AMAZING chemistry with screen vixen Eva Marie Saint. Both actors manage to light up the screen each time they are together and by the end of the movie, we are convinced that these two characters are truly in love.
