A ghost writer is hired to help pen the memoirs of an ex-prime minister who resembles Tony Blair but looks more like Pierce Brosnan. When a body turns up off the coast of Martha’s Vineyard and the PM is charged with war crimes, meeting that deadline seems more and more remote. Roman Polanski returns to thriller territory, with Robert Harris adapting his bestseller The Ghost. It’s our hope that Polanski exposes the political world as a pool full of Noah Crosses. The crazy cast, which includes Ewen McGregor and Kim Cattrall, suggests that it’s more likely to descend into absurdist nonsense.
