But as the old song says, "step by step they're putting it together," under a canopy that has been placed over the red carpet all the way into the Dolby Theater.
Oscar is under wraps - and so is his red carpet - but it is going take more than a few raindrops to tarnish him. Rain or shine, the stars are still going to come out on Sunday night.
An average of more than 40 million people in the U.S. watched last year's show when more young people tuned in to watch one of their favorites: Seth McFarlane. But his jokes were crude enough to cause controversy.
That led to this year's producers choosing to go back to the future with Ellen DeGeneres.
"I decided to host the Oscars again because I like a challenge and I don't like to get stuck in a rut doing the same thing every day," said DeGeneres. "So every once in a while I like to just challenge myself and this year I thought I would challenge myself in front of a billion people."
It's been called the toughest gig in all of show business and at any one time only a few people in the world can do it well.
"She's funny. She's warm. She's a Hollywood insider and she has enough perspective to give it the everyman point of view," said Neil Meron, who is producing the award show.
The producers enlisted Michelle Obama last year to present the Oscar for best picture and those in charge have new surprises planned this year.
But try as they might to keep the show fresh, the most memorable moments are usually the most unexpected.
"You guys are just standing up cause you feel bad that I fell and that's really embarrassing, but thank you," said Jennifer Lawrence after unexpectedly tripping on her way up to the stage last year.
Even veteran stars can get stressed out here - which is why Oscar's waiting room is like no other.
New York designer David Rockwell and Architectural Digest magazine have teamed up to make sure those stars appearing on the show feel soothed and truly pampered for the big show Sunday night.
