Jennifer Ehle's only career nude scenes. When asked about her several naked scenes during an interview, she said, "When I took the job, I didn't realize there would be so much of it, but no one forced me to do it. The first time I felt really shocked - then came a whole day of naked scenes. I went home and was physically sick. But it wasn't the time or place to sit down and ask why I'd done it. I'd forgotten that I'd be seen naked in a lot of living rooms."
Rebecca Hall was only ten years old on the broadcast of the series which was directed by her father, Sir Peter Hall.
Writer John Osborne was a friend of Maggie Smith, mother of Toby Stephens. He claimed her response to seeing the show was "It was really quite a shock. I hadn't seen his willy since he was two and a half."
