British actress Karen Gillan felt so relaxed shooting nude scenes for a new movie, she forgot she was naked.

The former Doctor Who star plays a novelist in romantic comedy Not Another Happy Ending and she has recalled how she forgot she had stripped off as the crew members were so professional on set.

She says, "I was really nervous beforehand, naturally I knew I'd have to sit there all day without anything on. Actually it was fine, they strategically covered me up with flesh coloured bits of material and also it was a closed set so there wasn't loads of crew guys walking around.

"Everyone was just very respectful and by the end I'd forgotten I didn't have any clothes on."

French heart-throb Stanley Weber co-stars in the film, which is due for release in the U.K. on Friday (11Oct13).
