Ben Affleck arrived at a LA studio this morning still modeling a shaggy hairstyle and wearing a purple t-shirt before changing into vintage bell bottoms and a sports coat. He's been spotted logging long hours on the set of his latest directing project, Argo, though Jennifer Garner, Violet, and Seraphina have stopped by to deliver hugs. Ben stars alongside Breaking Bad's Brian Cranston in the flick based on the true story of the CIA's successful rescue of six American hostages from Tehran in 1979. Besides his Hollywood projects, Ben's also excited to take the role of dad of three! The Garner-Afflecks announced Jen's pregnancy last month and Jen's since been proudly showing off her bump. Ben's new movie has him juggling responsibilities on and off camera much like The Town, which was a big hit at last year's Toronto Film Festival. He's he's not involved in the 2011 festivities, but Jen may head north for Tuesday night's Canadian premiere of her quirky, dark comedy Butter.
