Scripts for "Django Unchained," "Les Miserables," and "Beasts of the Southern Wild" are officially out of the running for Writers Guild Awards (WGA) because they, along with several other critically acclaimed films, were not produced in accordance to WGA submission guidelines.
Statistician Nate Silver has noted that industry insider awards, like the WGAs, are strong category predictors for the Oscars, but being left off by a technicality might not affect the chances for the films. As Deadline notes, being ineligible for the WGAs does not mean being ineligible for the Oscars: "Despite shared memberships, screenwriting nominees for the Motion Picture Academy seldom correspond 100% in either original or adapted categories because Oscar rules are less restrictive."
Hitfix notes that scripts for "Unchained" director Quentin Tarantino's films have gone on to winning Academy Awards despite him never having been a WGA member.
List of notable movies that are shut-out from the WGAs:
Original Film Category: "Amour," "The Impossible," "Middle of Nowhere," "Seven Psychopaths," "Take This Waltz," "Your Sister’s Sister" and "Brave"
Adapted Film Category: "Anna Karenina," "Beasts of the Southern Wild," "The Best Exotic Marigold Hotel," "The Intouchables," "Quartet," "The Deep Blue Sea," and "Rust And Bone"
