This week there has been talk of a third ‘Hobbit’ film after The Hollywood Reporter reported that sources close to the production of The Hobbit say the filmmaker Peter Jackson wants to turn his upcoming two-film adaptation of the J.R.R. Tolkien epic into a trilogy. While the first two films already have names – “The Hobbit: An Unexpected Journey” and “The Hobbit: There and Back Again” – it’s not officially known what the title of the third film will be. Unless, of course, you take a look at some recent web activity involving “The Hobbit” and the internet brand protection company MarkMonitor. Domain registrations made this week suggest the title may be “The Hobbit: The Desolation of Smaug” or “The Hobbit: Riddles in the Dark”.
