What is the name of the Lego game based on the movie The Lego Movie?

The Lego game based on the movie The Lego Movie is The Lego Movie Videogame.

Developed by TT Fusion and published by Warner Bros. Interactive Entertainment, the game was released alongside The Lego Movie in 2014. It follows the film's story and features its characters, including Emmet, Wyldstyle, Vitruvius, Lord Business, and Batman.

The game uses the series' familiar action-adventure formula of exploration, combat, collecting, and puzzle solving, but adds building mechanics tied to the film's Master Builder concept. Regular Builders use instruction pages to construct objects, while Master Builders can creatively assemble objects from loose Lego pieces.

A frequent mix-up is The Lego Movie 2 Videogame, which is based on the 2019 sequel The Lego Movie 2: The Second Part. Lego Worlds and Lego Dimensions also include Lego-themed settings, but neither is the direct game adaptation of the first movie. The stored title is therefore the precise canonical answer.
