Graham Greene was a very talented writer, who churned out several good works; this among them. The film stars two heavyweight actors, Anthony Hopkins and Derek Jacobi (after he ruled Rome in Claudius). The plot is ingenious and fascinating, and the tension in the film holds for over an hour. I was very happy to see that Greene did not opt for a typical Hollywood ending and stuck to his guns in the true Shakespearian sense. The film drips with Shakespearian devices and nuances. Highly recommended.
