I'm so grateful for a civilised film at last: it hardly matters to me what Literary Correct folk think of writer-director Neil LaBute's adaptation of AS Byatt's 1990 Booker Prizewinning novel. Not a lot, I imagine. Fancy replacing the earnest English scholar of the novel with an unkempt American, they'll say. Why, the chap doesn't shave. He wears big T-shirts outside his trousers, totes his research papers in a shoulder bag, describes his morning ablutions as "brush and flush", and is likely to bring the British Museum, where he works as a research assistant, into disrepute by discovering and impulsively purloining a hitherto unknown love letter. It's from Randolph Henry Ash (Jeremy Northam), a Victorian poet laureate, to Christobel LaMotte (Jennifer Ehle), a lesser-known literary lioness whom Ash makes his mistress.
