The Deadline Team :

Peter Jackson says he and his team are working ’round the clock to finish post-production on The Hobbit: An Unexpected Journey in time for its world premiere Wednesday November 28 in Wellington, New Zealand.

Comment by Peter:

It worries me when films are rushed to be finished in order to screen on a certain date. I have no doubts the film(s) will be just as enjoyable as the LOTR trilogy but it makes me wonder if we’ll be seeing the final product on Dec. 14th or will we have to wait for the extended editions again on discs?

I think Peter has something here.
