Leave it to Lupita Nyong'o to shut down the always amazing Cannes red carpet.

The super-stylish Star Wars: The Force Awakens actress stunned at the 2015 Cannes Film Festival Opening Ceremony on Wednesday in a bright green Gucci gown, embellished with crystal flowers. This being Lupita, she embraced the drama of the dress, highlighting all the layers of chiffon.

Her signature headband completed the memorable look.

Lupita wasn't the only one bringing the high-fashion to Cannes. Fellow Oscar winner Julianne Moore wasn't to be overlooked in a sparkly dark Armani Prive gown. Rocking a slicked-to-the-side 'do and smoky eyeshadow, the 54-year-old Still Alice star was the definition of gothic glamour done right.

Natalie Portman played it a lot safer in a red Christian Dior dress, but still looked gorgeous in the sleek design. The 33-year-old seemingly ageless actress kept it simple with sideswept locks and silver drop earrings.
