Ben Affleck gave a charming smile upon his arrival at the National Multiple Sclerosis Society's 38th annual Dinner of Champions in LA last night. He's back at home following a quick trip to Spain over the weekend. He was overseas promoting Argo at the
San Sebastián International Film Festival, which comes on the heels of his recent layover at this year's TIFF. Ben's heading into what could be a busy month with Argo opening Oct. 21. The Garner-Afflecks are also prepping to celebrate Samuel's first Halloween. We've seen his big sisters model costumes ranging from lambs to puppies in the past, so there's the possibility of an adorable outfit in his near future.
