The 63rd Annual Cannes International Film Festival officially kicked off today.

There to get a head start on the festivities were Kate Beckinsale, wearing a gorgeous lavender and plum sheath at the Jury Presentation Photocall, and Cate Blanchett, who looked chic in an Armani Privé Spring 2010 dress suit at the "Robin Hood" Photocall.

Check back every day this week for more red-carpet Cannes coverage.
