Oscar winners Natalie Portman, Julianne Moore and Lupita Nyong'o, along with supermodel Bar Refaeli and celebs, were all on hand for opening ceremony and the red-carpet premiere of La Tete Haute (Standing Tall) held at the Grand Theatre Lumiere, Palais des Festivals during the 68th Cannes Film Festival on Wednesday night. That's one good looking red carpet!

For the glittering night, Portman went bold with a custom red Dior gown which showcased her petite frame. Red-hot lady for a red-hot night in the South of France!

Still Alice's Julianne Moore, who is at the film festival as L'Oreal Paris ambassador, opted for a plunging Armani Prive design for the opening night event. The redhead contrasted her hair with emerald earrings and wore her hair in a side part and opted for dramatic eye make-up for the occasion.

Another stand out was Naomi Watts who turned up the glamor volume when she chose a feathered Elie Saab Haute Couture frock. What a stunner in silver!

Nyong'o couldn't help but twirl around the red carpet in her one-of-a-kind Gucci gown. We love the color but we aren't totally in love with the design. Keep your dress down, lady!
