This is a comparison of the Theatrical Edition (TE) and the Extended Edition (EE).

Unless otherwise noted, all times given are related to the Extended Edition.

The EE (not including end credits) is a total of 24 minutes, 43 seconds longer than the TE.


Result
The characters Bishop Aringarose, Silas and Bezu Fache are the ones that profit most from this extension. It allows us to find out considerably more about the shady schemes for Aringarosa and Opus Dei behind the Pope's back. More details about Silas' motives and background are given. In the TE this was clearly too short. Fache's connection to Opus Dei is made clearer and the scene, in which he apologises to Sophie and Langdon for his blind obedience, enhances his character considerably.

A great deal of further background information is also provided. It would, however, have been nice if Sophie's character had been fleshed out a little more. She has a strong scene in the Louvre, but sadly it still does not do justice to the character portrayed in the book. All in all, the EE provides a much more wholesome story than the TE.

Viewers who already found the theatrical version too long, have not read the book and are not interested in the backgrounds to the stories would be better off avoiding the EE. Others like me, who practically devoured the book whole and were rather disappointed by the TE, should give the EE a chance. There's still a lot missing from the book, e.g. Sophie's brother, the role of Andre Vernet, but this version makes the film a bit more worth seeing.
