Max & James Danielle

Max Ophuls is the legendary director and two of his favorite actors are James Mason and Danielle Darrieux. Mason and Darrieux were each in several Ophuls projects but were never together in an Ophuls movie, although they should have been. What might that movie have been like? It's anybody's guess (but cinephiles can dream, can't they?). Somewhere between a historical essay and a speculative one.
