Actress Joanne Froggatt has said she is "proud" of Downton Abbey for tackling its controversial rape storyline which has prompted complaints to ITV and regulator Ofcom.
The star, whose character Anna Bates was attacked by Lord Gillingham's valet Mr Green in Sunday's edition of the show, said it was a "brave" move by programme-makers.
ITV warned viewers about upsetting scenes before the start of the period drama, created by Julian Fellowes, but still received "around 60 complaints" by yesterday, with Ofcom also receiving an undisclosed number.
Froggatt said today: "I was really proud of the show for tackling a subject like this. It's a really brave thing to do and I really do believe that Julian's written that in a way that is not gratuitous at all, he does very much go on to explore the emotional journey of Anna and Bates.
"He's done a beautiful job of hitting the right note with it. I think we all just felt a big responsibility to get it right," she said during an interview on BBC1's Breakfast.
Froggatt, who was made aware of the storyline by producer Gareth Neame a week before she was given the script, said creators of the show did not want to show graphic violence on screen.
"J ulian, and this is a credit to him, was adamant that we wouldn't depict that kind of violence against a woman on the screen and that's something that he didn't want in a show of his, that he's a part of, and that's an incredible thing in this industry in this day and age," she said.
"And the shock value was there without having to depict anything graphic. The story is shocking enough, as it should be for a story of that essence."
She said she had prepared for the role by looking at the testimonies of women who had been through a similar ordeal in those days - as well as modern women who had been reluctant to report attacks.
"I did a lot of research on the internet reading through people's stories of women who have been through similar situations, and women that hadn't gone to the police in this day and age because they were in a situation that came across as being vague when they were going to explain it - maybe they were at party or it was someone they knew and they were very confused by what had happened to them. Now what I wanted to do - I wanted to get into my head as an actress - was to bring that to this time period."
She said the programme's historical advisor had pointed out that women still had few rights back then which made them reluctant to report such an attack.
"All you had was your reputation, your career, possibly if you had a job, and your family. There was still such a stigma attached to any sort of attack like this, that you were very much in danger of losing all of that.
"If a woman lost her reputation, that would bring shame upon the house - she could lose her job, she could lose her husband and society still saw it as no smoke without fire - 'he's only a man, he couldn't help himself'. it's very interesting to see that was only a hundred years ago," Froggatt added.
The episode was seen by an average audience of 9.2 million according to overnight figures.
Fellowes has defended the storyline and pointed out that the plot was not done for sensational purposes, but to explore the "emotional damage".
He told the BBC: "The whole point of the way we do things on Downton is we don't do them gratuitously. We are interested in exploring the resultant emotions and the effect these things have on people."
Fellowes added: "If we'd wanted a sensational rape we could have stayed down in the kitchen with the camera during the whole thing and wrung it out.
"The point of our handling is not that we're interested in sensationalising but we're interested in exploring the mental damage and the emotional damage," he said.
