Jennifer Garner was on the set of The Dallas Buyer's Club in New Orleans today with her two youngest kids. She carried her young son, Samuel, around between takes and also held hands with her smiling daughter Seraphina. Jen began filming The Dallas Buyer's Club earlier this month with costars Matthew McConaughey and Jared Leto. Her husband, Ben Affleck, has been hanging out in LA during her absence. He's on the West Coast with their oldest, Violet, who's in school. Yesterday, Ben took advantage of some downtime to run errands around their Brentwood neighborhood, and on Sunday, took himself out to do a bit of shopping.
