The new trailer gives a behind-the-scenes look at how Traveller's Tales has recreated the world of Middle-Earth with LEGO and included all three stories in a single game.
Announced earlier this year, LEGO Lord of the Rings encompasses the entire Lord of the Rings trilogy and features co-op multiplayer, as well as the series' usual dose of humour.
Players will be able to drop into key levels from a map of Middle-Earth, allowing them to return to previous areas and complete side objectives.
For the first time in the LEGO series, LEGO Lord of the Rings will feature actual dialogue taken from the films and performed by the original actors. Traveller's Tales last game, LEGO Batman 2: DC Super Heroes, also featured voiced dialogue, but this will be the first LEGO game using original voices from the source material.
LEGO Lord of the Rings releases for the Xbox 360, PS3, Nintendo Wii, DS, 3DS, PlayStation Vita and PC this autumn.
