I am trying to find out the title of a movie I saw years ago, on amc or tcm. It's a B&W film- maybe from the 40's? I think the title is the boy's name in the movie. The basic story is: these two children who are in love, they are separated at some point and then find each other again as adults. I remember hearing the song "i dreamt i dwelt in marble halls" in the movie. The movie feels like a dream and it's so beautiful. I'd love to find out more information. Can anyone help me?
