The Heat of the Day (1989) is a British film where the story takes place during the World War II, partly in London and, to a lesser extent, in Ireland. The film is based on a homonymous novel, published in 1949, written by Elizabeth Bowen and its screenplay is due to Harold Pinter. The film has espionage ingredients, but not very well explained. In my view most of the actors have quite an artificial and unconvincing performance in many scenes. However, the actress Imelda Staunton, who plays a small part in the film, in her two short scenes was able to upgrade the film to a higher level and after that, the film went back to being confused and aimless. In short, it's a boring movie.
