Colin Firth

Marion Cotillard donned a strapless Vivienne Westwood gown to join Colin Firth at the Chopard lunch as part of the festivities for the Cannes Film Festival today. Marion and Colin celebrated the jewelry brand, which is responsible for creating the festival's Palme d'Or trophy, as well as best actor and actress awards. The celebratory lunch comes at an interesting time for the brand since it was revealed that $1 million worth of Chopard jewels were stolen from a hotel room in Cannes last night. The jewelry was to be loaned as red carpet pieces to the stars at the festival. Many drew comparisons between last night's burglary and the film, The Bling Ring, which coincidentally debuted at the festival yesterday, since the movie is based on the real-life case of teenage burglars who robbed the Hollywood homes of celebrities.

There's lots of big news in this week's casting update, including the latest tidbit that Justin Timberlake has signed on to play '70s record executive Neil Bogart in a biopic. Meanwhile, Michael Fassbender and Natalie Portman are taking on Shakespearean roles, and small screen star Nina Dobrev will take a big screen role in a comedy. James Franco has found his next directorial project, and Colin Firth is in talks for not one, but two upcoming parts. Click through to find out where your favorite stars are headed next!

Emily Blunt and Colin Firth got together on the red carpet in LA last night for the premiere of their film Arthur Newman, which hits theaters in limited release next week. They were joined by their costar Anne Heche, who had her partner, James Tupper, by her side, as well as Emily's man, John Krasinski. The celebration continued with an afterparty, where John and Emily mingled with John's The Office castmate Kate Flannery. John has a little time on his hands to support his wife since he's wrapped filming on the final season of The Office and his next project, Monsters University, doesn't come out until June. He and Emily took advantage of the break to travel to the Caribbean for pal Matt Damon's vow renewal celebration last weekend. They landed at LAX on Wednesday night showing PDA and their fresh-from-vacation tans.

The Dubai International Film Festival held this year's Oxfam charity gala tonight with major Hollywood names like Rooney Mara, Freida Pinto, Kristin Davis, Colin Firth, and his lovely wife, Livia, all stepping out in their finest formal attire. Rooney stuck with her signature slicked-back locks and opted for a sheer and shimmery look from Calvin Klein. Freida chose a vintage red gown from Valentino, while Kristin kicked up her heels in vintage Dior.

The celebration is a reunion of sorts for Colin and Rooney, two of last year's award season favorites. Rooney earned her first-ever nomination for The Girl With the Dragon Tattoo, and Colin took home the Academy Award for best actor for his role in The King's Speech. He'll likely return to the Oscars this year as it's traditional for the previous winners to take part in the show. We're less than a month away from the kickoff of award season, with both the SAG and Golden Globe nominees announced this week!

Cameron Diaz, dressed in a sexy black and white design from Stella McCartney, hit the red carpet at tonight's London premiere of Gambit. Prior to the screening, she met up with costars Colin Firth, Alan Rickman, and Tom Courtenay to pose for photos. Cameron's been making the press rounds on behalf of the film in recent days and even landed the December cover of Elle UK. She opened up to the publication about her career, sex, and her forthcoming health and fitness book. Cameron shared why she strives to maintain her sleek frame and what she'd be doing if she wasn't an actress. Colin and Cameron's comedy caper flick hits UK theaters Nov. 19, but no official release date has been set for the States.

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.
