Ghost

This is called The Ghost Writer in other countries, and it has nothing to do with ghosts.
A rather bookish Ewan McGregor is commissioned to edit for publication the memoirs of Adam Lang a former UK prime minister played by Pierce Brosnan, and travels to America where he is living at the time.
He soon finds the apparently smooth running household to be in quite a turmoil. Adam Lang is indited for war crimes in the Hague, and the isolated location gets swamped with the press and protesters.  Meanwhile Ewan McGregor's character becomes more concerned about what happened to the previous ghost writer, and discovers clues that he left behind.
The best thing about the film is not the growing tension and intrigue, but the domestic tension inside the Lang household. There are some superb scenes, but Olivia Williams, who plays Adam's wife Ruth steals them all.
There is a cameo appearance from Eli Wallach, which is always good. Quite a good film, with some interesting twists along the way.
