Jennifer Garner and Steve Carell got animated on the set of their upcoming flick, Alexander and the Terrible, Horrible, No Good, Very Bad Day, in LA yesterday. Steve kept all of his little costars entertained as Jennifer had a laugh alongside him for the day in front of the cameras. The lighthearted day of filming comes after a much more intense session of shooting, in which Jennifer displayed a wide range of emotions for a hectic action scene with Steve and her adorable little costar last week. She's been dedicating much of her time to her new children's flick lately, but she did break from work to spend Labor Day with her little ones. Jennifer bonded with Samuel and Seraphina over an adorable park date in LA during her day off.
