Having made his name as Harry Potter, Daniel Radcliffe must now spend the years ahead stamping on his childhood image. He could take a lesson from Robert Pattinson, who appears in the astonishing new film Bel Ami, as the most charismatically repellent leading man I can recall. He makes Valmont in Les Liaisons Dangereuses look like a puppy. In another piece of counter-casting, Kristin Scott Thomas plays a lovesick matron, humiliatingly scorned. It is an unsettling premise that a handsome young man can pick off the wives of powerful men. Newspaper proprietors and politicians will keep a much closer eye on their domestic arrangements after seeing this film.
