With the social girls still meandering their way back from St.Tropez, the only party action this week came from Hollywood types. At the premiere for the Weinstein Company's live-action-and-CGI kids' flick Arthur and the Invisibles — which stars Madonna, David Bowie, and Robert De Niro all skipped — we ran into actors and brothers Rob and Nate Corddry, who voiced animated miniature people in the film.

Us: How did you get in the mindset of tiny, made-up people who live in the grass?
Nate: I didn't employ a moment of thinking in the two hours we spent doing these voices.
Rob: Not one second of preparation?
Nate: I thought about where the men's room was and where craft services was.
Rob: "Why did I drink the night before? Now my voice is hoarse. Am I stealing money from these people?"

Us: Well, if you were a miniature person, what would you do?
Rob: I'd be all over the place, just pulling pranks. Crazy pranks! Like throwing hats off people's heads and tripping their dogs.
Nate: Like a poltergeist! I don't care about being small. I'd like the ability to nap anywhere.
Rob: Isn't that called narcolepsy?
