Katie Holmes & Costar Luke Kirby Get Close On Set

By Maggie Coughlan

Business or pleasure?

Katie Holmes was photographed getting up close and personal with her costar on the set of her latest film, "Mania Days," in New York on Tuesday.

Wearing long jean shorts cut just above the knee and a white T-shirt, Holmes, 34, laughed with Luke Kirby as the duo walked alongside each other in front of cast and crew.

In another shot, Holmes is snapped pressing her forehead to Kirby's in what seems to be an an intimate moment. 

But it's no surprise the snapshots appear romantic "Mania Days" centers around two manic depressives who meet in a psychiatric hospital and fall in love.

Later, Holmes slipped on a cozy oversize sweater over her costume to fight the chill.

The film is slated for release in 2014.
