Since TIFF began, the seemingly tireless Emily Blunt has walked the Argo red carpet, snuggled up to husband John Krasinski at Soho House, hit the CAA party and, last night, worked the premiere of the dark comedy Arthur Newman with her co-star Colin Firth. In the film, Firth plays a man who fakes his own death, and draws a pill-popper named Mike (Blunt) into his scheme. The latter looked lovely in a recycled silk tulle Tory Burch dress, a show of support for Firth’s wife, Livia, who spearheaded the Green Carpet Challenge to encourage stars to wear eco-friendly duds. However, the night belonged to a blue-suited Mr. Firth, who was celebrating his birthday—begrudgingly. Apparently, Blunt and the film’s crew were forcing him out on the town after the premiere to mark the occasion (even though, according to Blunt, “He’s one of those people who doesn’t want to celebrate his birthday”).
