I Ask the Audience: Somebody Name That Film For Me

This has been bugging me over a couple of centuries..  In the early 1950s I was taken to the Odeon by a nanny who I suspect should have sat me in front of Pinocchio but no doubt came to the correct conclusion that if she gave me enough ice cream I would keep quiet and watch the film of her choice. I think it starred Judy Garland but  I could be wrong and then it will be impossible to identify I suppose.

 I may have taken my afternoon nap through most of it because I have just the one image  in my memory and that is the closing scene which involved a handsome man in a white towelling robe.

  He walked off the terrace down a couple of steps and dropped it on the sand.

Then he waded slowly into a sunset sea

never to return was the impression I had at the time.  Or maybe he was just having a pre-prandial dip but somehow it felt more dramatic than that.  Was nanny sobbing? I can't rightly remember.

I shall be very embarrassed if I have imagined all this and terribly grateful if anybody knows what I am talking about.   If you did see a film something like this,  forgive me if my visual aids have put you off it for ever.
