That’s the movie I was thinking of. I couldn’t recall the title. I think Christopher Reeves was in it. Late radio talker Art Bell used to bring that movie up several times a year.
Rachmininoff would have been at the top of his fame during that period, along with Schubert and his Trout Quintet Concerto. One of my favorites.
Christopher Reeve and Jane Seymour. Love the movie score too.
