You may have noticed that the big movie for this Christmas period is The Golden Compass, a $90 million adaptation of the first volume of Philip Pullman's His Dark Materials trilogy.
It's got talking bears, witches on broomsticks and Nicole Kidman, as the film's villain, Mrs Coulter. It's the best performance in a film that has many surprisingly smart casting choices (Tom Courtenay, Daniel Craig, Jim Carter, Derek Jacobi), despite its rather hamfisted handling of the source material.
