It is pretty disturbing! Since their intent was not sexual (and nakedness does not equal sexuality) I don't think it counts as sexual assault, but it would count as physical assault. Plus, the water must have been hot enough to scald her, and that is abuse. When I draw a bath and the water is steaming, that means it's too hot. (FYI I turned my water heater down to 120 degrees F after that.)
I agree with OP. It would certainly be considered assault/abuse now. When the movie was made, there was much less consciousness of treating people with respect, of oppression, of equal rights for women.
And just knowing he's on the street where she lives would be stalking.
Back in high school, I somehow learned a classmate lived on the same street as myself. I thought that was just enough to propose a date. I never heard from her. Now, there are a lot of reasons why she might have chosen not to respond, but I sometimes wonder if it was because of her Middle East background, and she may not have been allowed to be alone with a guy who isn't her husband or a relative.
My neighbor across the street once gave me a ride home from community college when my car battery died, and I think she caught hell for letting me into a car with her, hahaha. She just had this smile on the whole time we were traveling together, like ten minutes, maybe. Her father would bow to Mecca in her driveway, but I think he had passed on before our little dalliance.
Here's what happened: my internet was acting wonky again. I posted the message you responded to and went to get a cup of coffee, but the page froze after hitting the add-reply button. I refreshed the page when I came back to the computer and found to my utter horror (I'm easily terrified) that the post was now double-posted.
So, no clever quip, intelligent debate, or anything even trivial to add to what I had already said. How sad is that?
