Originally, the third film, The Battle of the Five Armies , was intended to be released as downloadable content (DLC) or a separate expansion. However, this was eventually canceled , leaving the game's narrative ending on a cliffhanger where Smaug flies toward Lake-town.

Unlike most LEGO games that cover an entire film series, LEGO The Hobbit only adapts the first two films: An Unexpected Journey and The Desolation of Smaug .

This is the second main story mission where the Dwarves arrive at Bilbo Baggins' home in Bag End.
