Jessica Chastain is a vision in flowing floral gown at Academy Museum Gala in LA

Jessica Chastain was among the stars to attend Saturday night’s annual Academy Museum Gala, which was held at the museum’s headquarters in Los Angeles.

The Academy Award-winner, 45, was a vision in a flowing white strapless gown with a vibrant floral pattern and matching floor-length cape.

Her toned legs peeked through two thigh-high slits in the show-stopping number as she strolled the red carpet.

Jessica rocked sparkling platform heels that gave her petite frame a boost.

Instead of jewelry, the Zero Dark Thirty actress debuted a metallic gold manicure.

Jessica’s head of lengthy auburn hair was tucked behind one ear and cascaded down her chest in glamorous curls.

Her pout was painted a glossy mauve shade and she dusted shimmering eyeshadow across her lids.

Julia Roberts is slated to receive the first-ever Icon Award at the Academy Museum Gala, which is being held this year for only the second time.

When it was held for the first time last September, the star-studded event managed to rake in a whopping $11 million for the new museum, per The Hollywood Reporter.

Other honorees this year include Doctor Strange star Tilda Swinton, who is being presented with the Visionary Award, which honors ‘an artist or scholar whose extensive oeuvre has advanced the art of cinema.’

The Vantage Award celebrating ‘an artist or scholar who has helped to contextualize and challenge dominant narratives around cinema’ is going to Steve McQueen, the director of 12 Years A Slave and Shame. 

Parasite producer Miky Lee, who also happens to be the vice chair of the Academy Museum board, will receive the Pillar Award in honor of her ‘exemplary leadership and support for the Academy Museum.’

Oscar-winning actresses Lupita Nyong’o and Halle Berry are chairing the gala with TV impresario Ryan Murphy and successful horror producer Jason Blum.

Former TCM host Jacqueline Stewart, who was named head of the Academy Museum in July, showered praise on Julia earlier this year when it was announced she would be presented with the icon award.

‘Over the course of her expansive and renowned career, Julia has embodied iconic characters and memorable roles. We are thrilled to be honoring her continued excellence in the industry and contribution to the arts,’ she gushed.

‘We are deeply grateful to Julia, Miky, Steve, and Tilda, to Rolex, and to our co-chairs and host committee for making our second annual Gala an evening to remember.’

Beaming! The duo looked handsome as they posed for shutterbugs 

The Academy Museum opened last year just four days after the first gala, igniting a storm of controversy over its political slant.

Critics slammed the museum for emphasizing the contributions of various minorities to the American film industry while all but ignoring the white Jewish immigrants from Central and Eastern Europe who played a major role in creating Hollywood.

The museum responded to the blowback by announcing this March that they will be adding a permanent exhibition highlighting the Jewish history of the movie business.
