Warner Bros. has announced a vehicle design contest for their upcoming LEGO movie, where one lucky fan will be able to see his or her work at use in the upcoming animated movie. The studio released a video on the movie's Facebook page, where you can find all the details you need to enter this unique contest. Warner Bros. also confirmed the news that Elizabeth Banks and Morgan Freeman have joined the cast, and released the first plot details. Take a look at the contest video, and read the official press release below for more information about this animated adventure.

Will Arnett, Elizabeth Banks, Chris Pratt and Morgan Freeman will lend their vocal talents to the LEGO world, starring as characters in the upcoming original 3D animated LEGO feature, currently in production, from Warner Bros. Pictures and Village Roadshow Pictures.

The film, the first-ever full length theatrical LEGO movie, follows Emmet, an ordinary, rules-following, perfectly average LEGO minifigure who is mistakenly identified as the most extraordinary person and the key to saving the world. He is drafted into a fellowship of strangers on an epic quest to stop an evil tyrant, a journey for which Emmet is hopelessly and hilariously underprepared.

Chris Pratt (Moneyball) stars as Emmet. Oscar winner Morgan Freeman (Million Dollar Baby) and Elizabeth Banks (The Hunger Games, Emmy nominee for 30 Rock), will star as two of Emmet's fellow travelers: Vitruvius, an old mystic; and tough-as-nails Lucy, who mistakes Emmet for the savior of the world and guides him on his quest. She also calls upon the mysterious Batman, a LEGO minifigure voiced by Will Arnett (Emmy nominee, 30 Rock), with whom she shares a history.

The 3D computer animated adventure will open nationwide on February 28, 2014.

Phil Lord & Chris Miller (21 Jump Street, Golden Globe nominee Cloudy with a Chance of Meatballs) are directing from their original screenplay, story by Dan Hageman & Kevin Hageman and Phil Lord & Chris Miller, based on LEGO construction toys. The film will incorporate some of the most popular LEGO figures while introducing several new characters, inviting fans who have enjoyed the brand's innovative toys and hugely popular video games for generations to experience their visually unique LEGO world as never seen before.

The film will be produced by Dan Lin (Sherlock Holmes, Sherlock Holmes: A Game of Shadows) and Roy Lee (The Departed, How to Train Your Dragon). It will be distributed by Warner Bros. Pictures, a Warner Bros. Entertainment Company, and in select territories by Village Roadshow Pictures.
