Warner Bros. is preparing a special novelty for LEGO fans: the company wants to release a feature film starring puppets and landscapes built with striking colorful and fitable pieces.

The 3D animation is slated for release on February 28, 2014 and will feature big-name movie stars like Elizabeth Banks and Morgan Freeman who will lend their voices to the little characters.

So far, it has only been reported that the plot tells the story of a LEGO character who is recruited to take part in a mission to prevent an evil LEGO tyrant from gluing the universe. The film will be directed by Phil Lord and Christopher Miller, who have released a video on the official website of the film asking Lego fans to produce any type of vehicle (the more different the better) with the parts and send it to participate in the.
