Sarah Jessica Parker dazzled in a white Dolce & Gabbana gown at The Weinstein Company's Vitamin Water-sponsored soiree in Cannes last night. Harvey Weinstein presented previews of their upcoming slate including My Idiot Brother, which debuted at Sundance, and My Week With Marilyn, which is out later this year and stars Michelle Williams as Marilyn Monroe. Sarah Jessica took the stage to present a five-minute peek at I Don't Know How She Does It, the romantic comedy she recently filmed. She admitted she was a bit nervous to show off the project in front of the crowd, but the funny and touching clips left me eager to see the finished product. The movie stars Sarah as a working mom trying to juggle her career and family, and it features an ensemble cast including Pierce Brosnan, Olivia Munn, Christina Hendricks, and Greg Kinnear. Harvey gushed a bit about Sarah up on stage, saying that his friend Anthony Minghella would have loved her for the part. SJP then changed and was off to the Cannes Film Festival premiere of TWC's Wu Xia. Don't miss all our coverage of Cannes straight from the action in France!
