Fair Game” screenwriters Jez Butterworth and John-Henry Butterworth have been named recipients of the Writers Guild of America West’s Paul Selvin Award.

The award, aimed at recognition of work that embodies the spirit of constitutional rights and civil liberties, will be given to the Butterworth brothers Saturday at the Writers Guild Awards West Coast ceremony at the Renaissance Hollywood Hotel.

“Jez & John-Henry Butterworth’s Paul Selvin Award-winning screenplay for ‘Fair Game’ expertly conveys both the impact and implications of a contemporary media climate where public and private worlds are often blurred for political gain,” WGA West prexy John Wells said. “Their absorbing script articulates nuances of political and personal speech, while adeptly maintaining a tight focus on the human-scale drama, illuminating the all-too-personal costs when our basic rights are put in jeopardy.”

“Fair Game,” released by Summit, was based on the books “The Politics of Truth” by Joseph Wilson (portrayed by Sean Penn) and “Fair Game” by Valerie Plame Wilson, played by Naomi Watts.

Jez Butterworth’s other co-screenwriting credits include “The Last Legion” and “Birthday Girl,” co-written with his other brother Tom Butterworth. “Fair Game” is John-Henry Butterworth’s first credited screenplay.
