Sacha Baron Cohen and Isla Fisher
Baron Cohen, 45, once commanded fees of £13m a film, but last year's Grimsby was a rare flop. Born in London, he shot to fame with his spoof gangsta Ali G in 1998, helping him to win best newcomer at the 1999 British Comedy awards. Da Ali G Show began in 2000, and won a Bafta for best comedy the following year. Baron Cohen’s films have taken more than $3.7bn at the box office; Borat and Brüno totted up nearly $400m between them. Based in Hollywood, he is married to actress Fisher, 41, whose movies include Wedding Crashers and Confessions of a Shopaholic.
