Yes, identifying by the back of the head is a tough one. But, makeup artist(s) would be close to the actors for touch-ups and Pierce and Gemora did work Rue Morgue together(among others). There is a great chance it is them. My opinion of course. I think Gemora might have been involved with Zita Johann's makeup. I do not know if filming overlapped with Mummy and Rue Morgue. Anyway, it's a cool photo:)
