Mila Kunis and Justin Timberlake joined their Friends With Benefits director Will Gluck in Moscow today for the Russian debut of the movie. Mila wore an Elie Saab couture dress that brought to mind her Black Swan ballerina role. Mila and Justin's new romantic comedy opened on big screens stateside last weekend, and while it came in third at the box office with $18.5 million, it was up against tough competition with Captain America and Harry Potter and the Deathly Hallows Part 2 also in theaters. Justin and Mila will now see how the film fares overseas, but she'll be back to work on her next project soon since production has already started on Oz: The Great and Powerful in Michigan.
