Oscars 2016: All the Details of the Governors Ball

— -- After all the Oscars are handed out at tonight's show, the celebrities will make their way to the official after-party: the Governors Ball.

The bash, which will be attended by some 1,500 people, has been in the works for more than six months, according to event producer Cheryl Cecchetto, the founder of Sequoia Productions.

Academy governor Jeffrey Kurland announced earlier this month that the theme of this year's party is art, and it will feature more than 170 black-and-white caricatures of celebrities from Alfred Hitchcock to Whoopi Goldberg.

"I thought to myself, 'We need to make sure we have a contrast of the black-and-white to a palette that will make them pop," Cecchetto told ABC News, adding that she decided on a pink palette. "When you walk in, all you see is the celebration of film."

However, the bright walls created a bit of a conundrum for Mark Held, of the florist Mark's Garden. To create a contrast, he and his team decided to use more than 10,000 white flowers, including calla lilies, gardenias, ranunculus, phalaenopsis orchids, roses and succulents, and pair them only with greenery.

"All the flowers we've chosen are important flowers that do stand on their own. They're sculptural and they have a relationship with Hollywood's history," he explained. "You see gardenias in someone's hair. The calla lilies you see Hepburn."

And while the stars are admiring the art on the walls and the flowers at their tables, they'll also be looking to chow down. Wolfgang Puck created 30 dishes for guests to try, including a poke, sushi and shellfish bar and a chocolate buffet. And while he's introducing a few new menu items this year (attendees should look forward to trying his made-to-order doughnuts) standbys including truffle mac 'n' cheese and chicken pot pie will also be available.

"If you're really hungry you can start maybe with some smoked salmon Oscars, then have a baked potato with caviar. Maybe have an apple celery soup with black truffles," he suggested. "You can always have a little Kobe steak with a little short rib if you like, or if you like fish, we have Dover sole. Or, if you like, we can make you a vegetarian or vegan meal!"

To wash it down, Sterling Vineyards will be serving 600 bottles of its limited edition Red Carpet Reserve, 260 bottles of its limited edition Gold Standard Reserve and 240 bottles of its reserve chardonnay. Haig Club cocktails will also be available, as will Piper-Heidsieck champagne. However only winners will have access to the rare Piper-Heidsieck Rare Millesime 1988, which will be served in the trophy engraving room.

Said the brand's global executive director, Benoit Collard, "This is a very special tribute from the house of Piper-Heidsieck to the great job they're doing."
