The ladies of Vicky Cristina Barcelona had jaws fully dropped when they hit the red carpet last night for the premiere of the highly anticipated Woody Allen flick at the Mann Village Theatre on in Westwood, CA.

Penelope Cruz displayed sartorial sophistication in a midnight blue plunging gown. The criss cross front gown had shirred chiffon tied on the waist that cascaded down the left side. She accessorized with blue drop earrings, a matching blue ring on the left hand index finger, a thin bracelet on her right arm and a black clutch.

Meanwhile, costar Scarlett Johansson looked striking in an off shoulder scarlet flowing chiffon gown by Monique Lhullier, which had a gathered neckline and was cinched at the waist to accentuate her shape. She accessorized with silver peep-toe heels, multi pendant necklace and of course her engagement ring from fiancé Ryan Reynolds.

In theaters August 15, Vicky Cristina Barcelona casts Scarlett as an emotionally and sexually adventurous American woman in Barcelona who becomes romantically entangled with a charismatic painter (played by new Oscar winner Javier Bardem) and his tempestuous ex-wife (played by Penelope).
