"Skyfall" beat off competition from fellow nominees "Before My Time" from "Chasing Ice" (J. Ralph), "Everybody Needs a Best Friend" from "Ted" (Walter Murphy & Seth MacFarlane), "Pi's Lullaby" from "Life of Pi" (Mychael Danna & Bombay Jayashri) and "Suddenly" from "Les Misérables" (Claude-Michel Schönberg, Herbert Kretzmer & Alain Boubil).
Three other Bond tunes have previously been nominated ("For Your Eyes Only", "Nobody Does it Better" and "Live and Let Die"), but "Skyfall" is the first to win. The last Bond film to win an Oscar was "Thunderball" in 1965, when it won in the Best Sound Effects category.
During her speech, Adele thanked songwriting partner Paul Epworth for "believing in me all the time." Dame Shirley Bassey performed "Goldfinger" at the bash, in a tribute to the Bond franchise which had recently celebrated 50 years.
"Skyfall", the 23rd official James Bond film, was a huge success and became the biggest grossing film of all time at the British Box Office.
