Oscar winning actress Catherine Zeta Jones has been getting down to some method acting for her latest role…which means getting her hands dirty!CZJ reportedly went undercover as a chef in a New York eatery and spent a week chopping and frying in Manhattan’s Fiama restaurant all as research for her forthcoming role in ‘Mostly Martha’.Chef Michael White said to People magazine: "She's been doing a lot in the kitchen - sautéing and cutting," "She's a great garnisher. Drizzling oil and balsamic on plates - she does a nice job.CZJ even turned her hand to a spot of waitressing one evening without the guests realising who she actually was.A fellow waitress said: "One night she did a little serving. A few people said to her, 'You look so much like Catherine Zeta Jones'."And she said, 'Oh, I get that all the time'."Method acting seems to be the ‘in’ thing in Hollywood at the moment. Reese Witherspoon will be delivering pizzas in London in preparation for her new film ‘Penelope’.
