Claire Foy has said filming sex scenes makes her feel "exposed" and "exploited".
The actress - who played Queen Elizabeth in The Crown - has claimed shooting intimate clips is the "grimmest thing you can do".
Claire, 37, is set to appear in the BBC miniseries A Very British Scandal over the Christmas period - taking on the role of Duchess of Argyll, Ethell Margaret Campbell.
The festive special will cover the British socialite's high-profile divorce in the 1960s, which featured explicit photographs and routinely made the headlines at the time.
Speaking on BBC Radio 4's Women's Hour, Claire opened up about how she feels about tackling scenes of an intimate nature.

"It’s a really hard line because basically you do feel exploited when you are a woman and you are having to perform fake sex on screen," she explained on-air.
"You can’t help but feel exploited."
The star added: "It’s grim – it’s the grimmest thing you can do."
Claire then went on to discuss how she didn't want her latest sex scenes to be reminiscent of certain "awful" movie counterparts.
"You feel exposed," she stated.

"Everyone can make you try to not feel that way but it’s unfortunately the reality.
"But my thing was that I felt very strongly that it had to be in it, but I wanted it to be female."
"I did not want it be that sort of awful climactic sexual experience you often see on the cinema screen," she confessed.
Claire's character in A Very British Scandal was at the time famed for her beauty, style and charisma.
But her infamous divorce saw accusations of violence, drug-taking, and bribery - with even an explicit Polaroid picture and scandalous testimonies becoming public knowledge after being leaked.

During her chat on the BBC radio show, Claire admitted the Duchess of Argyll was likely to be the first woman to be "slut-shamed" on a national level, but expressed her dislike of the term.
"I hate the phrase slut-shaming, I absolutely hate it," the actress admitted.
"But I think that women have basically been slut-shamed forever. I think Eve was probably slut-shamed."
She added: "There is something about it that I just hate, the rephrasing of the ownership of that title, and it being used in a way that justifies it even more.

"Just the word 'slut', I think, probably shouldn’t exist."
A Very British Scandal will air on BBC One over three consecutive nights, starting on Boxing Day.
The mini series is the work of the very same team behind the BBC's A Very English Scandal, which starred Hugh Grant and Ben Whishaw as politician Jeremy Thorpe and his lover, Norman Scott.
*A Very British Scandal begins at 9pm on BBC One on Boxing Day, and continues for the next two nights (27 and 28 December).
