The 68th Cannes Film Festival got off to a flying start in France, with stars walking the red carpet at the annual season opening.

Australia’s own Naomi Watts, who appears in Gus van Sant’s festival entry The Sea of Trees, wore a powder blue gown from Elie Saab Couture’s spring-summer 2015 collection, its top festooned with sequins and pearls above a flowing feathered skirt.

Not to be outdone, recent Oscar-winner Julianne Moore wore a silk gauze column dress by Georgio Armani Prive, adorned with aqua and black Swarovski embroidery and paired with a black feathered top. The flame-haired actor, who won Cannes’ best-actor prize last year for Maps to the Stars, offset the look with bold emerald earrings.

Among others, Natalie Portman, Jake Gyllenhaal and Sienna Miller also walked the Riviera red carpet ahead of the gala screening of Emmanuelle Bercot’s Standing Tall.

Best dressed guests included Lupita Nyong’o, Jane Seymour, gorgeous Chinese actress Viann Zhang and newly engaged model Bar Refaeli.rs_634x1024-150513101256-634.Naomi-Watts-Cannes.jl.051315rs_634x1024-150513110737-634.Julianne-Moore-Cannes-Red-Carpet.jl.051315rs_634x1024-150513101156-634-lupita-nyongo-cannes.ls.51315rs_634x1024-150513101525-634-natalie-portman-red-cannes.ls.51315  rs_634x1024-150513142225-634.Jane-Seymore-Cannes.ms.051315rs_634x1024-150513112011-634.Frederique-Bel-Cannes.jl.051315rs_634x1024-150513112558-634.Bar-Rafaeli-Cannes.jl.051315473192506
