The Beautiful Image (1951)

One day, Raoul Cérusier realizes with amazement that his face has changed. With the exception of an old uncle, no one, not even his wife, recognizes him. From an ordinary, rather ugly man, he has become a charming young man on whom the prettiest girls turn, including his wife whom he seduces. Fortunately, he regains his old face in time and Madame Cérusier, losing a lover, finds her husband again.
