What does the well-dressed movie director wear to shoot his movie? Apparently, not much. As actress Mary-Louise Parker told PEOPLE at last night's New York premiere of the episodic "The Five Senses," in which she plays a cake decorator who creates visual but bland-tasting stunners, director Jeremy Podeswa showed up on the set one day absolutely starkers. (A chronic prankster, Podeswa also once popped a mouse inside a cake to surprise Parker, she says.) Explaining his, er, working wardrobe, Podeswa told PEOPLE: "We said it was going to be a naked crew day, but I was the only one who showed up naked . . . The joke was on me."
