desolation of smaug poster Various sources are indicating that the next trailer for The Hobbit: The Desolation of Smaug will debut in very early October, and that it will be attached to the Warner Bros. film Gravity.

A first-time source of unconfirmed reliability tells that “Hobbit fans would be inclined to see Gravity.”

This correlates with the musings of some of TORn’s staffers, and a number of TORn messageboarders who have pointed out that Gravity is the last Warner Bros. movie to open in cinemas before The Hobbit: The Desolation of Smaug comes out on December 13. And, unsurprisingly, Hobbit trailers have a history of being attached to WB films. The trail of logic strongly suggests that Gravity is the prime candidate for the next DOS trailer.

In addition (and in support of this), our friends at tell us that a reliable source within the Russian distributors of the film tells them that:

The new trailer for “The Hobbit: The Desolation Of Smaug” will premiere at the very beginning of October. The trailer is labeled “Trailer #3” (with #2 being an abridged version of Trailer #1). The release will most likely happen simultaneously throughout the world. However, not every country will get a dubbed version immediately; the Russian version, for example, will be first released in English with subtitles.

The Trailer #3 is entirely new and not a re-edit of the previous trailer (although it shares some shots). The editing is finished; right now it is undergoing color correction and effects work.
