Emily Blunt and Colin Film Premiere at TIFF | Pictures

Colin Firth and Emily Blunt teamed up to premiere Arthur Newman at the Toronto International Film Festival last night. Emily stuck around the Canadian city after supporting her friend Ben Affleck at his TIFF premiere of Argo on Friday with her husband, John Krasinski; Ben's wife, Jennifer Garner; and their mutual pals Matt and Luciana Damon. For yesterday's big event, Emily paired Graziela earrings with a dress customized by Colin's wife Livia's Green Carpet Challenge. The white frock is an older number from Tory Burch, updated and made new again for Emily's big evening.
