In a video (below), some of the cast from The Hobbit: The Battle of Five Armies revealed that the World Premiere for the movie will be on December 1 in London, England at Leicaster Square. Considering most of the core cast and crew are either from the UK or from New Zealand probably most of them will be there. Part of it will include a live stream.
