For the fourth filmed version of Noel Coward's hit stage play "Blithe Spirit," director Edward Hall and his battery of script writers have managed to keep much of the ditzy original flavor of the Coward piece - it's still set in 1930s England - but also make it accessible to and funny for modern audiences.
The basic plotline is that Charles Condomine, an alcoholic novelist, has been hired to adapt one of his books into a Hollywood-bound screenplay. But he's suffering from writer's block, and can't type a word. Hold on, the problem is bigger than that. He isn't the person who wrote those books. Never mind the writer's block. He's never even been a writer. The books were ghost written, or more likely dictated to him, by his wife Elvira.
