LOS ANGELES (AP) — Christoph Waltz really owes Quentin Tarantino. Waltz won his second supporting-actor Academy Award on Sunday for a Tarantino film, this time as a genteel bounty hunter in the slave-revenge saga "Django Unchained."
In a choked voice, Waltz offered thanks to his character and "to his creator and the creator of his awe-inspiring world, Quentin Tarantino."
Waltz also offered gracious thanks to his supporting-actor competitors, who included two-time Oscar winner Robert De Niro and Oscar recipient Tommy Lee Jones, who had been considered a slim favorite over Waltz for the prize.
A veteran performer in Germany and his native Austria, Waltz had been a virtual unknown in Hollywood when Tarantino cast him as a gleefully evil Nazi in 2009's "Inglourious Basterds," which won him his first Oscar.
Waltz has since done a handful of other Hollywood movies, but it's Tarantino who has given him his two choicest roles.
The Scottish adventure "Brave," from Disney's Pixar Animation unit, was named best animated feature. Pixar films have won seven of the 12 Oscars since the category was added.
The story of an dauntless princess (voiced by Kelly Macdonald) who balks at her parents' attempts to marry her off, "Brave" won out over a strong field that included Disney's "Wreck-It Ralph" and "Frankenweenie."
"I just happen to be wearing the kilt," said "Brave" co-director Mark Andrews, who took the stage in his trademark Scottish garment.
Oscar host Seth MacFarlane opened with a mildly edgy monologue that offered the usual polite jabs at the academy, the stars and the industry. He took a poke at academy voters over the snub of Ben Affleck, who missed out on a directing nomination for best-picture favorite "Argo," a thriller about the CIA's plot to rescue six Americans during the Iranian hostage crisis.
"The story was so top secret that the film's director is unknown to the academy," MacFarlane said. "They know they screwed up. Ben, it's not your fault."
William Shatner made a guest appearance as his "Star Trek" character Capt. James Kirk, appearing on a giant screen above the stage during MacFarlane's monologue, saying he came back in time to stop the host from ruining the Oscars.
"Your jokes are tasteless and inappropriate, and everyone ends up hating you," said Shatner, who revealed a headline supposedly from the next day's newspaper with a headline reading, "Seth MacFarlane worst Oscar host ever."
The performance-heavy Oscars also included an opening number featuring Charlize Theron and Channing Tatum, who did a classy dance while MacFarlane crooned "Just the Way You Look Tonight." Daniel Radcliffe and Joseph Gordon-Levitt then joined MacFarlane for an elegant musical rendition of "High Hopes."
Oscar producers Craig Zadan and Neil Meron lined up a top-notch cast of stars as presenters, including "The Avengers" co-stars Robert Downey Jr., Samuel L. Jackson, Chris Evans, Mark Ruffalo and Jeremy Renner. They presented two prizes that went to the shipwreck tale "Life of Pi," cinematography and visual effects.
"This movie was quite a beast to make," said cinematographer Claudio Miranda, who shot dazzling images for the story of a youth adrift on a lifeboat with a Bengal tiger.
Miranda's win marked another round of Oscar futility for revered cinematographer Roger Deakins, who was nominated for the James Bond adventure "Skyfall." Deakins has been nominated 10 times but has yet to win.
Fans have pondered how far MacFarlane the impudent creator of "Family Guy," might push the normally prim and proper Oscars.
MacFarlane may be a wild card, but as for the show itself, predictability could be the Academy Awards' middle name. This time looks the same, with clear favorites in the main categories.
So Oscar organizers hope they've assembled a show that will be good time on its own performance merits, with wily, bawdy writer, director, animator, singer and all-around vocal talent MacFarlane as host and a ceremony packed with song and dance.
The awards themselves do hold some potential firsts and other rarities.
Affleck's "Argo" looks like it will be an uncommon film to claim best picture without a directing nomination, while "Lincoln" filmmaker Steven Spielberg and star Daniel Day-Lewis are favored to join exclusive lists of three-time Oscar winners.
Affleck was not counting on anything, though.
"We don't expect to depart with anything but our integrity," Affleck said on the Oscar red carpet before the show.
The ceremony will feature a tribute to British super-spy James Bond to mark the 50th anniversary of his first big-screen outing in "Dr. No." Adele will perform her Oscar-nominated title tune to last year's Bond tale "Skyfall," while the show features Shirley Bassey, who sang the Bond theme songs for "Goldfinger," ''Diamonds Are Forever" and "Moonraker."
The show presents a salute to movie musicals of the last decade, with "Chicago" Oscar winner Catherine Zeta-Jones and "Dreamgirls" winner Jennifer Hudson joining "Les Miserables" cast members that include best-actor nominee Hugh Jackman, supporting-actress front-runner Anne Hathaway, Russell Crowe, Helena Bonham Carter and Amanda Seyfried.
Affleck's thriller "Argo" is in line for best picture after winning practically every top prize at earlier honors. Hollywood was shocked that Affleck was snubbed for a directing nomination, possibly earning the film some sympathy votes, particularly from actors, who love it when one of their own succeeds behind the camera.
The story of how Hollywood, Canada and the CIA teamed up to rescue six Americans during the Iranian hostage crisis, "Argo" would become just the fourth film in 85 years to claim the top prize without a best-directing nomination and the first since 1989's "Driving Miss Daisy."
The best-picture prize typically ends the Oscar show, but this time, MacFarlane and Kristin Chenoweth will perform a closing number on the Dolby Theatre stage that producers Zadan and Meron called a "'can't miss' moment."
