Phil Lord and Christopher Miller (Cloudy with a Chance of Meatballs) are powering up their Lego feature film with the addition of Batman and Superman.  The film, now titled Lego: The Piece of Resistance, stars Chris Pratt (Parks and Recreation) as Emmet, an "instruction worker" in the Lego world who has zero creative skills and can only build from the provided manual.  When he is mistakenly identified as a legendary MasterBuilder, Emmet reluctantly embarks on a quest to prevent an evil tyrant from gluing the world together.  Lego: The Piece of Resistance, itself an 80/20 blend of Lego-animation and live-action, also features Robot Chicken director Chris McKay as a co-director under Lord and Miller.  Hit the jump for more on the project, including who will voice the Lego superheroes.

Variety reports

that Will Arnett (Arrested Development) will star as Batman with Channing Tatum (Magic Mike) being courted to voice Superman.  Tatum previously starred in Lord and Miller's 21 Jump Street, but has yet to confirm casting in Lego: The Piece of Resistance due to his busy schedule (the reshoots for G.I. Joe: Retaliation, Secret Service thriller White House Down for Sony, Bennett Miller's Foxcatcher and a major upcoming picture with the Wachowski Siblings.)  Arnett, on the other hand, has signed on to voice Lego Batman.  No stranger to animated features, Arnett has voiced a number of characters in such pictures as Ice Age: The Meltdown, Ratatouille, Horton Hears a Who!, Monsters vs Aliens, Despicable Me and The Secret World of Arrietty.

Look for Lego: The Piece of Resistance in 3D in theaters starting February 28th, 2014.
