TakePitch Perfectstar Anna Kendrick, for instance.

The famous actress has gone to great lengths to avoid exposing herself on the big screen.

Here are actresses who surprisingly refuse to bare it all and their reasons for choosing to remain clothed.

Jessica Simpson

Jessica Simpson

Jessica Simpsonhas a fantastic figure, and she doesn’t venture to cover it up.

Those accolades mean nothing to me….

I don’t think people deserve to see what’s underneath my clothing.

Sarah Jessica Parker

That’s only for my next husband ha ha ha!"

Parker even had a clause in her contract and opened up about it during an interview withThe Hollywood Reporter.

“I’ve always had one, and it’s apropos of absolutely nothing,” she said.

Rebel Wilson

“Some people have a perks list and they are legendary.

They have to have white candles in their room.

I don’t have a crazy list like that.

Mandy Moore

I’ve just always had [a no-nudity clause].”

She told the publication, “I think it’s fantastic that people feel comfortable doing it.”

She explained how it came up while filmingThe Brothers Grimsby.

Julia Roberts

“[They] wanted full-frontal nudity.

We write in the contract, specifically, ‘No nudity.’

They got in another girl this larger burlesque dancer from South Africa to be a nude double.

Ashley Benson

And they got her to do all this stuff.”

“I’m like, I’m not doing it.

I don’t care what you say,” she said.

Kristen Bell

To act with my clothes off is a documentary."

It made her [Roberts] look a little more curvaceous, just gave her that body she needed.

She said, “I make it clear that I have a line.

Rachel Bilson

Everyone tries to push you, and it’s easy to get talked into doing those things.

But not everyone realizes they can do that.”

She said, “But I don’t show my crack!

Jennifer Garner

Skins of the world are like, ‘Ooh, Kristen gets naked!’

I’m like, ‘Dream on!'”

Good for her for sticking to what she believes in.

Jessica Alba

Bilson toldPlayboymagazine (viaPeople) that movies can still accomplish their end result “without showing things.”

“It’s almost a deal breaker,” the former star ofThe O.C.said.

Both stars, however, said that they would never appear completely bare on screen.

Anna Kendrick

Gervais exclaimed, “There’s no chance of me doing it!”

And Garner stated, “I will not be taking it all off!”

The world deserves better.

Keira Knightley

The reason is that she doesn’t want her family members to seethatmuch of her.

It would be weird at Christmas.

Six years later she had still not changed her mind.

Lena Headey

She opened up toE!

“It’s not a natural thing to do,” Headey said.

Hilary Duff

Hilary Duff likely won’t be baring it all onscreen anytime soon if ever.

“If I do a movie I want to be myself,” Duff told the publication.

She continued, “I don’t want to take my top off or anything.

Instead, she’s far more concerned about embarrassing her future children.

Allison Williams

She’ll change her mind,'” Williams said.

“There are just certain things boys should never see their mothers do,” the actress explained.

“I don’t think my children should ever see me doing some of that stuff.

I don’t think my boys could handle that,” theTransformersstar noted simply (viaIndependent).

“Do you feel your penis isn’t big enough to show off on camera?”

Stern asked, to which Jackson reasoned it isn’t “formidable” enough.

As Kunis reasoned, she wasn’t unwilling to show everything, noting, “I showed side-boob.”

However, she would never “give away everything all at once,” according toThe Hollywood Reporter.

Naturally, she stood her ground and proved him wrong.

Roberts also frontedScream Queensas the instantly iconic Chanel Oberlin.

Presumably her toughest role yet isplayingmother to son Rhodes.

Watson, in particular, has emerged as a vocal feminist and civil rights activist.

She also went back to school, completing her degree in English literature at Brown, asE!

She’s not known as a sexpot actress, and, as Fischer revealed, that’s by design.

She reportedly toldPlayboymagazine he’d asked whether she’d “ever do a raunchy sex scene in a movie?

Like really raunchy, with nudity?'”

Shockingly, Bitterman allegedly told her, “You’re not a real actress, then.”

Thankfully, Fischer wasn’t swayed, and her subsequent career success speaks for itself.

Fisher also worried that showing a woman naked robs her of her comedic appeal.

“My first thought would be: ‘What would my mother think?'”

“Anytime someone talks about your figure constantly, you get nervous, you get really self-conscious.
