I don't know if fight club could be called Fincher's best film till date but I'm sure it is no less good!
Fight Club's greatest strength lies in the way it has been made. The content is great but great contents does not necessarily make great movies. Chuck Palahnuik deserves credit for coming up with a dark novel that its share of fun, action and mystery. It is primarily the brilliant construction of the novel that has laid the foundation for this film. Jim Uhls has made the screenplay smartly. The use of voice overs, and the dialogues add much strength to the content of the film and also to the character of the narrator. Working on a film of this sorts and having no name for one of the lead actors is just crazy.
Fight Club has a plot twist that hits you right in your head. The film has left its clues but I realized everything only on my second viewing. There is the David Fincher stamp of filmmaking all over fight club. The way the camera would move from one place to another breaking all those physical boundaries is not just visual fun but it adds a lot to the viewing experience. The way Fincher has treated his environment and portrayed the film from the point of the narrator is remarkable. Watch out for the very opening sequence in the film or the way the narrator character, of Edward Norton, visualize his friends Tyler Durden and Marla Singer, played by Helena Bonham Carter, on bed! Fincher's genius is all over fight club.
The casting makes the viewing convincing. Edward Norton is perfect with his voice overs and his screen presence and transformation over the acts makes is remarkable. I never got to see Brad Pitt in Fight Club. It was Tyler Durden and he was too freaking good.
Fight club is bloody violent, loud and tricky. The narrative might even seem odd and stale for a little part in the second act. But fight club worked for me, and it was not just once but also a second time.
