‘The Hobbit: The Desolation of Smaug’ Teaser Trailer: We (Finally) Get to See a Dragon

The titular dragon finally makes an appearance in the first teaser trailer for “The Hobbit: The Desolation of Smaug,” which hit the web Tuesday. It’s a quick glimpse — he sniffs around for his would-be killer, Bilbo Baggins (Martin Freeman) — but enough to whet appetites for the final showdown between the beast and the hobbit and dwarves who’ve come to end him off.
