Portman, 23, plays a stripper in the movie and filmed scenes featuring her romping nude in a topless club.

However, she said she became nervous about seeing the footage on the big screen asked Nichols to cut out the topless shots.

Nichols agreed and Portman tells Entertainment Weekly, "He wants to see my bare ass much less than even my father would.

"He's as or more protective of me than my parents are. So doing sexual, physical stuff for him felt very uncomfortable."
