Austrian actor Christoph Waltz got the 82nd Academy Awards off to a great start by picking up the event's first prize.

The heavy-favorite "Inglourious Basterds" star claimed the Best Supporting Actor honor, calling his award "uber bingo".
The big night opened with a special treat when all 10 lead actors and actresses nominated appeared on-stage at the Kodak Theatre in Hollywood.

As the hopefuls took their seats, Neil Patrick Harris took the stage to lead a glitzy song-and-dance number. The actor previously dismissed reports he would be part of an Oscars opening performance.

Co-hosts Steve Martin and Alec Baldwin then took the stage in style, floating down from the roof on a platform with a bevy of beauties, and then poked fun at nominee Meryl Streep, their It's Complicated co-star.

Martin joked, "Meryl Streep holds the record for most nominations as an actress, or, as I like to think of it, most losses."

He added, "Anyone who has ever worked with Meryl Streep always ends up saying the same thing: 'Can that woman act?' and, 'What's up with all the Hitler memorabilia?'"

And Helen Mirren was in for a chuckle when Martin said, "There's that Damn Helen Mirren," prompting his co-host to correct him: "Steve, that's Dame Helen Mirren."
