Constance Cummings and her accent
We're wonderful! She had a lapse OT two back into "American", but I thought her English accent was pretty good (I'm no expert on areas' dialects, but I thought she did a good aristocratic Brit accent).
I'll stand by my statement, but my delight in her accent MAY have been helped along by watching Sarah Paulson butcher a Britidh accent in American Horror Story.
