Katie Holmes was back at work on the 'Son of No One' set yesterday, but she was lucky enough to get a visit from Suri. I'm always struck by how happy Katie looks when she's filming. Look at her smile down there while she's sitting in the car: she just looks thrilled to be back at work!

Suri even seemed to enjoy herself: look at her laughing with her nanny in the thumbnails. Even the crowded set and paparazzi all over couldn't keep her somber for too long :)
