Naomi Watts hasn’t been nominated for an Oscar since 2004 (21 Grams), but she may be in the running this year for her work as CIA agent Valerie Plame in Fair Game.  Watts reunites with her 21 Grams co-star Sean Penn in the movie, which screened at the Cannes Film Festival.  The actress was inspired playing Plame, whose covert identity was revealed by Washington Post journalist Robert Novak.  Watts details her research on Plame, whose memoir serves as the basis for the Doug Liman (The Bourne Identity, Jumper) directed drama.  (CLICK ON THE MEDIA BAR BELOW TO HEAR NAOMI WATTS)
