George Clooney, Rooney Mara, Mila Kunis, and More Stars on Set!

The Cannes Film Festival kicked off this week, but some of our favorite Hollywood stars were still hard at work on sets in the US. Rooney Mara continued filming The Bitter Pill in NYC, while Ben Stiller and Adam Scott got physical on the set of The Secret Life of Walter Mitty before Ben headed to Cannes. Mila Kunis and Clive Owen were in character as bride and groom on the set of Blood Ties, and in LA, George Clooney stole our hearts cozying up to an adorable pooch on the set of a commercial. For all this goodness and more, click through to see which stars were on set this week!
