Sure Argo won the Academy Award for Best Picture, but let us analyze what other films won big that year.
Tom Hooper's well produced Oscar bait musical theatre "movie" Les Miserables won 3 awards and was probably stolen from Lincoln's Production Design (?) award, so it was really like 4. It was basically a big win for him.
Silver Linings Playbook earned the Big Five nominations, which will no doubt be notable for its additional win for Jennifer Lawrence.
Amour has its nomination for Emmanuelle Riva in addition to her BAFTA win, the Palme D'or and its Foreign Language Film nominations. Big wins for Riva, Hanneke and other acting legend Jean-Louis Tritgnant
Life of Pi was the biggest winner with 4 wins, including Best Director. It also dominated Argo, when it came to nominations.
