An elderly man living in an extremely modern house has his wife’s lover as a guest. He decides to play a game with him.
What unfolds is a minimalistic film that plays mostly in one house and has only two actors: Michael Caine and Jude Law, whose characters try to outwit the other. This makes an alright film.
What makes the film somewhat better is that it is a remake of a film from 1972 in which Michael Caine played the wife’s lover. Caine certainly has a sense of humor.
