As is often the way with alpha luvvies, Emma Thompson would hate to be thought of as putting on airs. She is West Hampstead, not Hollywood, so is all about pickling her own veg and keeping the Oscars in the downstairs loo, darling. When I turn up to meet her at home in north London, I get the house number muddled, so am having a chat with the actress Phyllida Law, her mother, who lives opposite, when we turn around to find the movie-star daughter standing in the middle of the street she has always lived on, in dungarees and comedy clogs on a Friday afternoon, squawking: “Oi! Don’t listen to that mad old woman! Come away from her! Come over here!”
