It's at the end of the new trailer for the video game from The LEGO Movie that the info falls, written in tiny: Gandalf will make an appearance in the game.
Indeed, in the credits given to the various rights holders, the following appears: " Gandalf appears courtesy of New Line Productions ." The wizard will therefore make an appearance in the game, but we obviously don't know the extent of his potential involvement in the game's events.
Below is the new trailer for the game which will be available on February 14, 2014 on all current platforms.
