This movie works for many reasons but the most powerful one is that you simply cannot stand anyone who would dare treat Ingrid Bergman this way! Charles Boyer is someone I’ve enjoyed onscreen in movies like Cluny Brown and History is Made at Night but his turn here is truly diabolical.
Angela Lansbury’s character feels like it could have gone darker in pre-Code days. There are hints of this but the film doesn’t develop that possibility.
I love what Bergman does in the finale. (For a second I thought I was in for a very different type of ending.)
