Since my posting of Best Films Of 2013, it has come to my attention that the Writers Guild has nominated Before Midnight as an Adapted Screenplay because the characters come from the films Before Sunrise and Before Sunset. While I would argue with that, it is what it is, so I'm changing my 2-way tie for Best Adapted Screenplay to a 3-way tie and adding a new film as Best Original Screenplay.
Best Adapted Screenplay – (a tie)
Winter – The Wolf Of Wall Street
Petroni – The Book Thief
Linklater/Julie Delpy/Ethan Hawke – Before Midnight
