Anna Kendrick was pressured to agree to nude scenes as a teenage actress

In the scene, Cheryl says "not for me" when asked if she would be willing to bare all, prompting a male casting director to gesture towards her breasts and say: "Oh, I'm sure they're fine."'.

Anna grew emotional as she told The Guardian newspaper: "That is lifted verbatim from something that happened to me when I was 19. Oh boy...

"I've, um ... I've had experiences where I found out there was a wardrobe change that the costume designer had been cagey about, likely because she felt her hands were tied. It's like you can't get to the bottom of it: 'Wait - sorry - um, why would I be in a bathing suit in this scene?' "

The 'Pitch Perfect' star was quick to stress her experiences are less common these days.

She added: "But I'm grateful that this happens a lot less now. And when you say you're uncomfortable, there's more of a culture of being taken seriously."

Anna previously revealed she had spent five years in a coercive relationship and she's admitted she still has "good days and bad days" in recovering from the abuse she experienced.

Asked how she feels now, she said: "I have good days and bad days. But it's more accurate to call them good months and bad months.

"If you'd asked me three years ago, I would have said there was something almost embarrassing about that. Like: 'Aren't you over it by now?'

"But I guess I feel a lot grosser saying, 'I'm doing great.'

"If we speak in another five years, please God tell me I'm not still struggling then, you know? I don't know how much of that feeling is based in my pure desire to feel OK versus: 'That'll mean I'm such a weakling.' It's all still swirling around in there somewhere.

"[My therapist] says: 'Grief has tentacles.' Meaning that whenever there's some minor challenging event in the present, it reaches back to more challenging things in the past. Sometimes I feel this specific event in my life is with me all the time and I wish I could just put it away."
