The transformation scene three quarters of the way through the dark medieval fairy-tale of an 80s movie, Ladyhawke, is possibly one of the most wrenching thwarted-love scenes in all of cinema.
I believe this movie holds up quite well despite the intervening decades. The cast is is strong (and features an incomparably beautiful young Michelle Pfieffer), the locations stunning, and the story full of action, pathos and humor in nearly equal parts. I've always held an affection for its Alan Parson's produced soundtrack - albeit, so very 80s in feel. The opening credits are still a nice watch - they are designed so beautifully.
