Katie Holmes hopped in a fountain at Washington Square Park in NYC today to film scenes for Mania Days. Her costar Luke Kirby accompanied her on the fountain run, and the onscreen duo splashed around for the cameras before they dried off and Katie headed over to pose for pictures with two little girls.
Earlier in the day, Katie and Luke took to a park bench to shoot more personal scenes, in which they exchanged several laughs and held hands. This was not the first glance of costar chemistry, though, since last week Katie and Luke got close while filming in front of a church. Work on the romantic drama, which deals with two manic depressives who fall in love, began a few weeks ago but is not expected to hit theaters until late next year.
