If anyone has anything else to add I would be very happy Thanks! However, if you want to see Ruth Collins naked or topless, then this blog post is where you should be! Bottom Line: Wyatt didn't do the scence.
It's an unknown actress seen only briefly in The Sign of the Cross.
We may be seeing much more than was originally possible with the equipment that existed back then, however back then we were probably looking at a Joan Bennett who was 25 feet tall on your average screen.
