“It took a while to shoot the scene by the coconut stall at the fun fair, so Michelle (Mary) and I had a competition. I think she beat me 10-1 - she was uncannily good. The crew were very disappointed in me. To be beaten by a woman is bad enough, but one in Edwardian dress is really highlighting something.”

“Michelle Dockery is Mary: There was one scene where I had a corset visible, so it was made for me. After we had filmed it, we removed all the details - flowers and ribbons - to make it a plain corset and then I could wear that as it was a perfect fit. I'm taller than most actresses, so most corsets tend to be to short in the body.”

“Susannah Buxton, costume designer: These three dresses demonstrate well the different ways in which we brought the costumes together for the show. Mary's dress was made for her, Edith's was hired - it was previously used in the Merchant-Ivory production of A Room With A View - and Sybil's is an original Edwardian summer dress.”

“There's an independence about Mary - she's not influenced by anyone and she's very much her own person, she makes her own decisions. I understand her because I'm one of three girls too and I've always been defiant that I didn't want to do what they did.”

“Mary is a very well-written typical eldest child in that she puts her own needs at the forefront... She's not as inclined to conciliate or placate. Cora is fascinated by Mary”

“Mary feels she should have been a boy and then everything would have been so much easier. She fights against her femininity in a way.”

“Laura Carmichael is Edith: During the war, Edith learns to drive the family car. "I haven't got a driving license, so I think production were a bit nervous! But in some ways it was an advantage that driving isn't second nature to me because I wasn't so surprised about where the things were. My heart was in my mouth - the car is one of the last of its kind and worth half a million pounds. The gears are all in a straight line and neutral is a tiny point in between, you have to do double declutching - so I just kept it in first. On the second take I thought I was thought o kill the cameraman! We were filming in Bampton so all the locals were watching, just to add to the pressure...”
