I guess the only surprise among the WGA nominees today is the Best Original Screenplay nom for James Cameron‘s Avatar. This, I presume, was a recognition of good story bones — the well-configured structure and the way it all pays off like a slot machine in the fourth act — more than the dialogue, which few seem to admire.
The other mind-bender was nominating Jon Lucas and Scott Moore‘s script of The Hangover in the same category.
Otherwise congrats to nominees Mark Boal (The Hurt Locker), Joel Coen & Ethan Coen (A Serious Man), Scott Cooper (adapted screenplay nominee for Crazy Heart), Nora Ephron (Julie & Julia), Geoffrey Fletcher (Precious), Robert Orci and Alex Kurtzman (Star Trek) and Jason Reitman and Sheldon Turner (Up in the Air).
