Summit Entertainment has picked up North American distribution rights to Doug Liman's Fair Game, starring Naomi Watts and Sean Penn, about outed CIA agent Valerie Plame.

According to Variety, Summit also has picked up rights for Italy, Benelux, Scandinavia, Japan and CIS.

Acquisition ends days of buzz about a possible domestic deal for the film, which attracted renewed interest from buyers after being accepted into the Cannes film festival. Fair Game is the only U.S. title in main competition.

Fair Game is based on Plame's memoir of the same name. The adapted script was penned by Jez Butterworth and John Butterworth.

In 2003, Valerie Wilson's cover was leaked to the press after her husband, former ambassador Joseph Wilson had criticized the Bush administration's rational for the Iraq war. She became the center of a political scandal and eventually resigned from the CIA in 2005.

"Fair Game is a very strong engaging thriller that will keep audiences on the edge of their seats. The performances are fantastic and Doug Liman has once again delivered a powerful film that harnesses all of the creative means at his disposal," Summit co-chairs Patrick Wachsberger and Rob Friedman said.
