Les jeux sont faits

I saw this film in the early 1950s, I believe, and I have never forgotten it. I can't find a listing of it as a video production in any format and wish that it could be restored and shown again. It is a touching story of an aristocratic woman and a working-class tough who die and meet in the afterlife. They fall in love and apply to a registry to get a second chance at life on earth. The conditions being that they stay together and make a success of their union. I particularly remember the depiction of the afterlife, which is populated with people costumed from several past eras, who stroll unseen in the contemporary world. A haunting visual experience and a touching drama.
