TWO ORPHAN VAMPIRES (Les Deux Orphelines Vampires) follows Henriette and Louise (Isabelle Teboul and Alexandra Pic), two blind girls of unknown origin, raised in an orphanage by two adoring nuns. Little do the nuns know, each night as the sun goes down, their "little angels" acquire night vision (they "see blue"), as well as an appetite for blood and teenage mischief.
Rollin's entire filmography, more or less, could be summarized as a poetical consideration of death, termination, and unreality, but coming to terms with his own pending death had a way of affecting how he regarded them (the film was undertaken just as he was diagnosed with kidney failure). Something previously conceptual and child-like, nostalgic and precious in Rollin's work becomes more concrete and dimensional, unflinching and adult. When they commit one violent transgression against their kindly benefactor, the scene's abrupt and awkward brutality recalls the best of Henri-Georges Clouzot.
