The book is quite excellent, you can hardly put it down. The 1947 movie is superb, and in fact was written by Greene, who later expressed his satisfaction with it. The ending is different, although anyone with her eyes open will see that the contrived trick of the movie ending leads inexorably to the bleak book ending. Richard (not David) Attenborough, later the "Jurassic Park" guy, gives a chilling performance as the heartless Pinkie. Most of the Catholicism is gone from the movie, and the narrative is tightened. It moves along quickly, the cinematography is very impressive, and the supporting roles are expertly handled. "Brighton Rock," by the way, is a type of stick candy sold there that has the word "Brighton" extending all the way through the stick.
