Carey Mulligan Pictures in Long Dark Wig

Carey Mulligan showed off a new look yesterday on the NYC set of Inside Llewyn Davis. She was practically unrecognizable in a long, dark wig. Carey spent a day shooting in and around the Big Apple's Washington Square Park with Max Casella. It was another of her leading men, though, who kept her company last week. Carey worked with Justin Timberlake a few days ago, and JT's fiancée Jessica Biel even swung by to say hello. Jessica has since returned to LA to work on a project of her own called Emanuel and the Truth About Fishes. Tomorrow's actually Jessica's 30th birthday — we're celebrating with a look at Jessica Biel's best bikini moments. Carey's own fiancé, musician Marcus Mumford, has yet to be photographed spending time around the production of her and Justin's Coen Brothers-directed project.
