Neil LaBute Will Find Out Who Poisoned The Old Man
"[T]he story is told from the perspective of Charles Hayward whose fiance refuses to marry him until the identity of the person who poisoned her grandfather is found."
That sounds like the kind of psychosexual tension that LaBute specializes in. The screenplay is by Julian Fellowes, who previously wrote the Christie-like screenplay for Gosford Park that Robert Altman ignored. Fellowes is also working on an upcoming ABC miniseries about The Titanic, which will commemorate the 100th anniversary of the ship's meeting with an iceberg. (via The Playlist)
