What are the differences between the Theatrical Version and the Director's Cut?
In September 2009, del Toro announced that he was working on a Director's Cut. Due to other obligations on his part, it was just recently finished. Now, 14 years later, the Director's Cut can be bought exclusively on Blu-Ray. It also features an audio commentary, in which del Toro shares some interesting information about the Director's Cut. Guillermo del Toro probably really wanted to improve his movie, however, he did not succeed in doing so. The viewer does not gain any new insights in the story and the characters do not get more depth either. The extensions are only additions concerning the plot and there does not seem to be any reason why the director's cut was released as Unrated. Most likely, this just happend to spare the costs for another MPAA classification. However, interesting is that a rather unintentionally funny scene was removed from the theatrical version.
The improvement in picture and sound quality is really significant. Through the use of color filters, the picture in the Director's Cut got a really threatening mood, especially in the underground scenes. A detailed comparison between both versions with pictures can be found here.
