Visual Effects -
Favorite: Life of Pi at 1/20
Next Best: The Hobbit at 10/1
Life of Pi is a Mortal Lock to win Best Visual Effects. It was beautiful. End of Story.
Sound Editing -
Favorite: Les Miserables at 1/6
Next Best: Skyfall at 15/2
Les Miserables is a Lock for Best Sound Editing. "You know they actually sang, right?" said everyone everywhere when recommedning this film.
Sound Mixing -
Favorite: Zero Dark Thirty at 10/11
Next Best: Skyfall at 11/2
This one is too close to call, but to be fair I have no idea what separates Sound Mixing from Sound Editing. Nobody in Vegas does either.
Production Design -
Favorite: Les Miserables at 5/4
Next Best: Anna Karenina at 6/4
Production Design is a dead heat, and is actually one of the closest races of the night. Also in the mix is Lincoln at 9/2.
