City types might find themselves attracting unusual attention from an American in a black polo neck over the next few days. Script writer Stephen Schiff is in London doing research for the sequel of the movie Wall Street that goes by the working title of Money Never Sleeps.

Drawing inspiration from the fast-money hedge fund era, and Michael Douglas reprising his role in the original, the 20th Century Fox production relies on Mr Schiff's considerable skills as a writer for the New Yorker and scriptwriter on a remake of Lolita. The onetime musician and film critic for Vanity Fair was hired at the New Yorker by Tina Brown, herself in town for the launch of her Princess Diana biography.
