'Always be yourself. Unless you can be Batman.' That's the sage like wisdom dispensed by a new one sheet that just arrived today. The poster is celebrating Batman Day. And what better way to do that than with the Lego mini-fig of everyone's favorite billionaire turned caped crusader, the Dark Knight?

In the irreverent spirit of fun that made The LEGO Movie a worldwide phenomenon, the self-described leading man of that ensemble, LEGO Batman, stars in his own big-screen adventure: The LEGO Batman Movie.  But there are big changes brewing in Gotham, and if he wants to save the city from The Joker's hostile takeover, Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up.

The LEGO Batman Movie is directed by Chris McKay. He is best known for directing several fan-favorite episodes of the Adult Swim series Robot Chicken. He also served as a director on the animated show Moral Orel. He is working from a script by Seth Grahame-Smith, Chris McKenna, Erik Sommers, Jared Stern and John Whittington. This creative team is working with characters created by the great Bob Kane and Bill Finger for DC Comics.

Rounding out the cast are Rosario Dawson as Batgirl and Ralph Fiennes as the Butler Alfred Pennyworth.

The movie is Produced by Dan Lin, Roy Lee, Phil Lord, and Christopher Miller. They are joined by Executive Producers Chris McKay, Ryan Harris. The movie swings into theaters on February 10, 2017, and will provided some great Valentine's Day counter programming as it goes up against the hugely anticipated R-rated sequel Fifty Shades Darker. It will also be going up against the R-rated action sequel John Wick: Chapter Two starring Keanu Reeves.
