Films that did not make the WGA grade include Rabbit Hole, Get Low, Hereafter, Shutter Island, Somewhere and You Will Meet a Tall Dark Stranger from writers' fave Woody Allen, which were also ignored by the PGA.
The full list of nominees is on the jump.
Of the expected documentary nominees, only Inside Job, Enemies of the People and Gasland are on the Oscar short list. PGA-nominated Client 9: The Rise and Fall of Elliot Spitzer and Waiting for Superman were significant omissions, while Banksy's Exit Through the Gift Shop was again a no-show.
The winners will be announced at the 2011 Writers Guild Awards on Saturday, February 5, 2011.
