With a budget of 150 million dollars the second film based on one of Dan Brown's novels made a little less than half a billion dollars at the box office worldwide. Compared to The Da Vinci Code the film is noticeably better paced and better in general but fans of the book have still been pretty critical about it. The film had a running time of 2:20 hours in the Theatrical version so when an Extended Version was announced for the home cinema market one had to wonder if it could really improve the film because additional running time is not always a good thing.

And in deed, the additional plot scenes are anything but necessary to keep the story going. Far more interesting are the violence extensions which outnumber the other changes. Additional to new scenes some shots look like blood has been removed for the Theatrical release in the US in order to secure the PG-13-Rating (for sequences of violence, disturbing images and thematic material). The MPAA gave the movie an R-Rating, anyway, and gave the desired PG-13-Rating only after approximately five minutes were cut out. Unfortunately, we do not know if the Extended Version is identical to this original version, but the violence extensions that can be witnessed here are definitely worth an R-Rating.

Those who did not like the Theatrical version will surely not be convinced by the Extended Version but it does leave a rougher impression.

Additional scene
0:15:45:
Cardinal Strauss talks to his colleagues and when he sees Father Simeon he says goodbye to them to walk a bit with him.
Simeon reports that Commander Richter assured him that his men do anything to find the four Preferiti (favorites to the pope-succession). He suggests that Strauss should already begin the ceremony before the cardinals are found and freed but Strauss responds that this is impossible because they are not electable that way. He also dismisses the possibility to candidate himself because he is chosen to lead the election ceremony.
After that Simeon mentions that the camerlengo asks how long he should wait until the next announcement to the public. Cardinal Strauss says that it takes as much time as the cardinals need and that another announcement to the public is not necessary. Simeon's objection that the people might think that something is wrong is interrupted by Strauss who says that people will think what they are told.
