“Vertiginous Variations on Vertigo” (110 minutes, 2016) is the third of a trilogy of films I’ve made in relation to Hitchcock’s films, the first two being “Variations on Guilt and Innocence in 39 Steps,” 2013, which investigates “The 39 Steps”; and “Mother and Son; or, That Obscure Object of Desire (Scenes from an Anamorphic Double Feature),” 2006, which views Sokurov’s “Mother and Son” from the standpoint of “Psycho.” The film composes a variant of Hitchcock’s “Vertigo” in which, among other things, Scottie’s drive for reenactment and repetition is not satisfied once he has made Judy look exactly like the beloved he lost, Madeleine.
