In the film, they have also cut out the character of Paul completely, as well as that of Oriol, the police officer who John knows personally. In addition, the movie eliminates all feelings of loyalty between Robie and his former Maquis comrades, who, in this version, are intent on deceiving and betraying him. All of this is, in my opinion, a mistake, as it leaves John without motivation... if not for his compulsion to aid his fellow Maquisards, what reason does he have for not escaping to the States? And without Paul- and to a lesser extent, Oriol- there are no conflicting feelings or divided loyalties. This eliminates a lot of the dramatic elements. What is left is a movie with a good central idea, but a generic plot with one-note characters and an obvious outcome. It's not that the film is bad- it's Hitchcock, after all- it's just that it dispensed with most of what made the book so great, resulting in a pale and inferior imitation. I'll stick with the novel.
