Hitchcock Didn’t Have a Belly Button: Karen Black Interview by Johan Grimonprez(2009)

During the making of Double Take, professional Hitchcock doppelgänger Ron Burrage pointed director Johan Grimonprez to a story doing the rounds online: supposedly, the Master of Suspense didn’t have a belly button. This captured the imagination of Grimonprez, as it implied that Hitchcock had not actually been born at all—an interesting extra layer on the hall of mirrors he was constructing in Double Take.
