I Know Who Killed Me — Until very recently, the prospect of this movie might have seemed utterly tantalising. Perpetual train wreck Lindsay Lohan plays a stripper, and famously suffered bruises all over her body when she got all Method-y and actually trained for the role on a pole. It might have been fun, if only in a late-night, laugh-out-loud kind of way. Now, after yet another arrest and further evidence of a worsening substance abuse problem, it just seems sad — a sad waste of talent, a sad lack of judgment, a sad course for a promising career. But the film itself, which wasn’t screened for critics before opening day, would have been horrendous anyway; place any other actress in the part and it’s just another straight-to-DVD release. Lohan stars as both Aubrey, an aspiring writer who goes missing, and Dakota, an exotic dancer who wakes up in the hospital with parts of her right arm and leg sawed off. Investigators (Garcelle Beauvais-Nilon and Spencer Garrett) and Aubrey’s parents (Neal McDonough and Julia Ormond — you read that right, Julia Ormond) swear the girl is Aubrey. She keeps insisting she’s Dakota. Does she have amnesia? Is she delusional? Or maybe she’s identical twins, and this is The Parent Trap <$>with pasties. R for grisly violence including torture and disturbing gory images, and for sexuality, nudity and language. 105 minutes. One star. — Christy Lemire
