Actress Natalie Portman insists she'll never bare all on the big screen again after regretting a saucy scene in new short film Hotel Chevalier.

The shots of the actress baring all in the film hit the internet earlier this year - months before the movie hit festivals in September.

And Portman admits she's rather upset about agreeing to do something she felt awkward about in the Wes Anderson-directed prelude to The Darjeeling Limited.

She says, "I'm really sorry I didn't listen to my intuition. From now on, I'm going to trust my gut more. Sometimes the most powerful thing you can do is say no."
