By the Gods!

Hans von Borsody and Antonella Lualdi in MASSACRE IN THE BLACK FOREST

The fellow in the Roman uniform is supposed to be Cameron Mitchell but we never see his face. It's one of the oddest thing in otherwise good production : just with 5 minutes or so remaining of the film, Mitchell, who was previously seen fighting for his life, suddenly disappears and a stand-in takes his place and we never see Mitchell again. Mitchell is main star of the film and yet it ends without showing him. The camera is set-up in a way as not to see who's in the Roman costume. I wonder what happened during the production. I haven't seen any talk about this oddity anywhere on the internet.
