Nicole Kidman filmed scenes for her upcoming thriller, Before I Go to Sleep, in London yesterday. She continued her understated look for the film, which included wearing minimal makeup and sporting a shorter 'do. Nicole jumped back to work after wrapping up filming for Grace of Monaco earlier this year and premiering her newest project, Stoker, back in March. We spoke with Nicole's Stoker costar Matthew Goode about working with the Oscar-winning actress, and he revealed that she is very down-to-earth. He said, "I was a bit worried about meeting Nicole, she's a huge star. She's completely charming, very funny, and very intelligent, super professional, works very hard, so passionate about doing this project."
