The people behind tonight’s Oscars show are urging people to tune in early for one of the show’s best sequences.

Bill Mechanic, who is producing the ceremony with Adam Shankman, promised “the most dynamic opening, from drama to spectacle to humor, that has ever been staged.”

Mechanic said the show will be heavy on humor, thanks to the hosting duo of Steve Martin and Alec Baldwin; he added that the Oscars hasn’t had two hosts since 1928.

Expect “greater emotional content” too, Mechanic said: “We want this to touch people.”

The Oscar honchos also announced a new round of presenters: Tom Hanks, Robin Williams, Cameron Diaz, Jennifer Lopez, Sarah Jessica Parker, Demi Moore, Zoe Saldana and director Pedro Almodovar.

Oscars special ending

Barbara Walters says tonight’s Oscars special, her last, will also be her best. On the show, at 7 on ABC, she chats with actresses Sandra Bullock and Mo’Nique, both nominated for Academy Awards for “The Blind Side” and “Precious,” respectively.

By bidding adieu, Walters is ending a 29-year tradition of talking to celebrities on Hollywood’s biggest night.

While Walters, 80, is known for getting stars to often tear up on camera, she says the celeb interview has become less special in recent years.

“I don’t find it harder to interview celebrities now,” she said. “I find it harder to interview a celebrity who hasn’t been all over the place.”

So while she’s walking away from her special, she’s not done with TV.

“I am not retiring!” Walter insists. “I will still be doing ‘the 10 most fascinating people,’ I will still be on ‘The View,’ which I love. I will still be doing pieces for ABC News.”
