With its complex twists and turns, AS Byatt's doorstopper of a novel Possession is hardly the kind of tale that translates easily to film, even though its switches in time across more than a century are intrinsically filmic. In this adaptation the basic story revolves around two modern-day academics, Maud Bailey (Gwyneth Paltrow, a class act, all ice and severe hair) and the young American Roland Michell (the charmingly diffident Aaron Eckhart). They find themselves thrown together as they track a secret love affair between two fictional Victorian poets, Randolph Henry Ash and Christable LaMotte (Jeremy Northam and Jennifer Ehle, both of them eminently convincing costume-drama veterans). As our two modern-day sleuths uncover the truth they (surprise, surprise) find themselves falling for one another.

Director Neil LaBute may have strayed from familiar territory (Nurse Betty) but he's managed to translate book to screen with compelling directness, and much credit should go not only to the four leads, but also to Lena Headey, who plays the tragic Blanche Glover, LaMotte's rejected lover. Overall it's a very lyrical movie, visually a treat for the eye, with the period detail beautifully caught and much beautiful scenery to be had. And the score itself, by Gabriel Yared, seems to encapsulate England in its pastoral beauty. Yes, of course the intricacies of the novel are much simplified, with some characters written out altogether, but its central spirit is retained and it makes for an ultimately compelling experience.

On the DVD: Possession has a pleasingly sharp and well-defined picture quality that makes the most of the fabulous visuals. However, extras are limited. As well as a list of cast and crew and the usual scene selections and theatrical trailer there's the option of watching the film accompanied by LaBute's commentary, which is enlightening first time around but probably not for repeated viewing. --Harriet Smith
