The Conjuring With Final Cut in Cinemas
There are many directors that use the opportunity of making a director's cut on DVD/Blu-ray when they had to make compromises for the theatrical version. And there are many directors that are happy with their theatrical cut but don't care when more (and often rather redundant) scenes are added later on in order to make an Extended Cut. James Wan, the director of The Conjuring, told Collider that he is fond of the idea that his films stay with one version only. He calls alternate versions for the home video releases a "cheat". Still, even his own works were affected by that. With Saw, he did it himself to reverse MPAA censorship. Whether he was involved in the making of the Unrated Cut of Death Sentence (that doesn't add real unrated material), is unknown.
Still, he doesn't plan anything in that regard with The Conjuring, even though he stated that he cut 20-30 minutes out of the final theatrical version. Fans may have liked this to be included in the film but he also confirms that this is mostly material like scene extensions and not all real deleted scenes that introduce something new and relevant.
The Conjuring has already started in US cinemas and is very successful there, even though it has an "R" rating because the MPAA denied the film the "PG-13" because they deemed it too scary (see here).
