Great list! I’d like to give a nod of the head to the transformation(s, mostly the more explicit second one) of Eddie Quist in “The Howling,” notable for Eddie’s exhibitionist attitude. He totally gets off on how physically repulsed his victims are. Also, one of my most favoritest tricks for on-screen transformations sadly only works in black and white, and was brilliantly used in both the 1931 “Dr. Jekyll and Mr. Hyde” and Bava’s “Black Sunday.” The actor’s make-up is done in red, and the key light is gelled red, so the makeup is invisible. Gradually, that light is turned down, while an adjacent green-gelled key is turned up, contrasting with the make-up and resulting in an apparent transformation of the actor’s face.
