To everyone who has not read the book - Please read the book! This film is a perfect example of how to murder a book. Death on the Nile is Agatha Christie's one of favourite works, as she writes herself in the introduction to the book. It is sad how trivial the film has made that book. The charcoal on the burnt cake is how the film gives an explanation to the origin of the famous mustache of Hercule Poirot!
