A polite, prissy take on Wilde which seems to think he wrote for children. Rupert Everett and Colin Firth are there, of course, as a playboy and a country mouse, both posing as “Earnest” while ducking scenery-munching from the tragically overrated Judi Dench and, in the token Gwyneth role, Reese Witherspoon. Muffs every joke as lamely as a fifth-form production.
