Based on the novel by Alice Hoffman, THE RIVER KING is a little known film that is quite haunting and involving. Edward Burns is wonderful as Abel Grey, a small town policeman investigating the apparent suicide of a young student at the local prep school. John Kapelos effectively plays his not so honest partner. As Burns investigates, evidence suggests that the victim did not kill himself, that he was perhaps murdered.
The movie is methodically paced and features beautiful Nova Scotia scenery; Burns becomes romantically involved with one of the teachers (a delightful Jennifer Ehle), who is engaged to another stuffy teacher. Rachelle Lefevre as Carla, the victim's best friend, is also very good. THE RIVER KING takes some subtle plot twists, one involving the suicide of his older brother when Abel was a child and this event plays a key part in Burns' investigation. Alternately moody and grim, the movie is nonetheless a very good one, and benefits largely from Burns' strong presence, and a lovely score by Simon Boswell.
And look at this IMDB thread where her performance in the film is discussed. Warning, the first poster isn't very nice, but the rest are.
