WellInformedYid,
I don’t know what you found on Google or whether it was accurate or not. (Sometimes searches turn up material that was edited out of the “final cut” of a film.)
I can tell you this that I remember no sex scene from the film. I have a different explanation than yours. I believe that either there was none or it was very insignificant.
Hakatan,
I believe you are well intentioned but I disagree with you.
First of all, a number of the actors were definitely Jewish.
Second, if you truly believe that watching a film of actors playing Jewish soldiers killing Nazis makes (in your words) “yourself a lesser person as a result of watching it” then I can only say you are lucky that my father, my uncles and my grandfather are in Olam Habah and not here to set you straight. As Holocaust survivors, they all would have loved the movie.
