Katie Holmes filmed a passionate kissing scene with her costar, Luke Kirby, on the set of her film Mania Days in NYC yesterday. The PDA didn't stop there as the duo embraced for another romantic scene together in a different location. Shooting for her latest project has had Katie packing in many different activities around the city. She and Luke held hands to film a scene as they played in the Washington Square Park fountain last month. It's no surprise that Katie has been getting romantic in front of the cameras with her costar since Mania Days follows the story of two manic-depressives who meet in psychiatric hospital and fall in love.
