Emma Watson was all in the spotlight on the red carpet as cast members of Noah arrived for the US premiere of the film in New York. The film releases on 28 March.

The 23-year-old Harry Potter star was a head turner in Oscar de la Renta black ball gown. The vintage-looking backless gown featured shell cut neckline, bow clinched on waist on the back and train.

A plunging V in the back gave Emma an elegant look as she flaunted it well by sporting a side-sweeping bun.

Emma paired her classic satin black gown having cascading layers with a pair of Christian Louboutin shoes and a Roger Vivier gold clutch.

Emma, who stars in biblical film Noah alongside lead actors Russell Crowe and Jennifer Connelly, completed her opulent ensemble by adding a rock twist to accessories.

She wore a diamond-encrusted ear cuff and an intricate gold wrist cuff by Aurelie Bidermann and Jennifer Meyer.

The actress kept her makeup subtle with dark nails, red lipstick, brows and lashes.

For the after party, Emma was quick to switch from her classic look to a party freak. She opted for trendy black dress gauze-like material featuring a floral appliqué all over, according to Mail Online.
