When Deborah Kerr’s Sister Clodagh chases after Kathleen Byron’s Sister Ruth in the phantasmagoric climax of Black Narcissus (1947), a dissolve spins Sister Clodagh from one room to another, briefly letting Clodah’s ghosting robes erupt through the floor in the same shot.
Here, a dissolve is used in an image on image, but not in a lazy Michael Stoops manner, but rather to accentuate panic and confusion. It’s also a unique editing strategy employed in a film that has several editing registers used throughout. It is probably not a coincidence that the same editor, Reginald Mills, worked on both of the Powell and Pressburger productions The Red Shoes and Black Narcissus. Click here for a gif.
