Shirley Bassey sung her classic Bond "Goldfinger" theme, Barbra Streisand honored Marvin Hamlisch with his Oscar-winning "The Way We Were" and Michelle Obama turned out to be the biggest surprise of the evening
William Shatner helped Seth MacFarlane kick off the 85th Annual Academy Awards by telling him he was "the worst host ever." Costumed as Capt. Kirk from "Star Trek," Shatner showed MacFarlane headlines from the future which were a result of tasteless jokes, a song about boobs and sexually harassing Sally Field backstage.
"Harry Potter" star Daniel Radcliffe and "Lincoln" cast member Joseph Gordon-Levitt joined MacFarlane during the opening number to swing and sing "High Hopes," from 1959's "A Hole in the Head."
Christoph Waltz won Best Supporting Actor for his portrayal of Dr. King Schultz in "Django Unchained" and thanked Quentin Tarantino -- the same man who directed Waltz in "Inglourious Basterds" -- for writing him yet another Oscar-winning role.
At 76, Shirley Bassey proved age is just a number by belting out her classic "Goldfinger" theme, during a 50th-anniversary tribute to 007.
Jennifer Hudson was the best part of the Oscar's tribute to musical movies, singing her "Dreamgirls" showstopper "And I Am Telling You I'm Not Going" -- the film earned her an Academy Award in 2007.
Adele reminded Hollywood why she deserved an Oscar for writing Best Original Song "Skyfall" by singing a flawless rendition of it, minutes before she returned to the stage to accept the award.
Barbra Streisand was one of the most highly anticipated performances of the night and she delivered by singing Marvin Hamlisch's Oscar-winning "The Way We Were" just moments after the late composer was honored during the In Memoriam segment.
When Chris Terrio excitedly took the stage to receive his first Oscar, for writing "Argo," he thanked director Ben Affleck -- who won his first Oscar 15 years ago for writing "Good Will Hunting" -- for making it possible.
Michelle Obama was the biggest (and possibly only) surprise of the night, appearing via satellite from the White House to introduce the nominees for Best Motion Picture before opening the winning envelope and crowning "Argo" as champ.
Ben Affleck wasn't recognized by the Academy for directing "Argo," but during his acceptance speech, he offered this piece of advice to make it in Hollywood: "Don't hold grudges."
