Jorge Luengo Ruiz studied, through a video compilation, the presence of a high voyeurism in Hitchcock’s movies. Actually, there’s always a character who’s watching something, someone else, who spies with binoculars and through keyholes. Among these films, we find The 39 Steps (1935), Young and Innocent (1937), The Lady Vanishes (1938), Rebecca (1940), Foreign Correspondent (1940), Notorious (1946), Strangers on a Train (1951), Rear Window (1954), To Catch a Thief (1955), The Trouble with Harry (1955), Vertigo (1958), North by Northwest (1959), Psycho (1960), Marnie (1964), Topaz (1969), Frenzy (1972) and Family Plot (1976).
