Although his relationship with Selznick was
stormy, he created several fine and notable features while working for the producer, either directly for Selznick or on loan to RKO and Universal, including Spellbound (1945), probably the most romantic of Hitchcock's movies; Notorious (1946); and Shadow of a Doubt (1943), considered by many to be his most unsettling film.In 1948, after leaving Selznick, Hitchcock went
through a fallow
period, in which he experimented with new techniques and made his first independent production, Rope; but he found little success.
