According to imdb, Sally was the uncredited victim.
Nor is it she in the ape photo, as Ham Radio has already explained that that is fan dancer Sally Rand.
It's an unknown actress seen only briefly in The Sign of the Cross.
If imdb is wrong then how can we trust them for uncredited info? Clémentine is a little more relaxed about nudity and has appeared in the raw on several occasions.
Elissa remains fully clothed throughout the film.
