<P> Emmet finds himself in the human world as a Lego minifigure unable to move . The events of the story are being played out by a little boy named Finn on his father's expansive Lego set in their basement . His father, "The Man Upstairs", comes home from work and chastises his son for ruining the set by creating variations of different playsets, and proceeds to permanently rebuild and glue his perceived perfect creations together (causing Lord Business' forces to regain the upper hand as a result). Realizing the danger his friends are in, Emmet wills himself to move and gains Finn's attention . Finn returns Emmet and the Piece of Resistance to the set, where Emmet now possesses the powers of a Master Builder and confronts Business . Meanwhile, Finn's father looks at his son's creations and realizes that Finn had based the villainous Business on him and his perfectionism . Through a speech Emmet gives Business, Finn tells his father that he (i.e. his father) is special and has the power to change everything . They reconcile and start to unglue the constructions with mineral spirits, which plays out as Business having a change of heart, capping the Kragle and ungluing his victims . Emmet is hailed as a hero and begins a relationship with Wyldstyle with Batman's blessing . </P> <P> As a result of Finn's father allowing Finn's younger sister to join them in playing with his Lego sets, aliens from the planet Duplon beam down on the Lego world and announce their plans to destroy everyone before the film ends in a cliffhanger . </P> <Ul> <Li> Chris Pratt as Emmet Brickowski, an everyman and construction worker from Bricksburg </Li> <Li> Will Ferrell as Lord Business, president of the Octan Corporation under the name President Business <Ul> <Li> Ferrell also plays "The Man Upstairs", a Lego collector in the live - action part of the film </Li> </Ul> </Li> <Li> Elizabeth Banks as Lucy "Wyldstyle", a Master Builder </Li> <Li> Will Arnett as Bruce Wayne / Batman, a DC Comics superhero who is a Master Builder and Wyldstyle's boyfriend </Li> <Li> Nick Offerman as MetalBeard, a giant makeshift pirate and Master Builder </Li> <Li> Alison Brie as Princess Unikitty, a unicorn - kitten and Master Builder from Cloud Cuckoo Land </Li> <Li> Charlie Day as Benny, a "1980 - something space guy" who is a Master Builder </Li> <Li> Liam Neeson as Bad Cop / Good Cop, a double - faced police officer that leads the Super Secret Police <Ul> <Li> Neeson also voices Pa Cop, Bad Cop / Good Cop's father </Li> </Ul> </Li> <Li> Morgan Freeman as Vitruvius, a blind old wizard who is one of the Master Builders </Li> <Li> Channing Tatum as Clark Kent / Superman, a DC Comics superhero who is one of the Master Builders </Li> <Li> Jonah Hill as Hal Jordan / Green Lantern, a DC Comics superhero who is one of the Master Builders </Li> <Li> Cobie Smulders as Diana Prince / Wonder Woman, a DC Comics superhero who is one of the Master Builders </Li> <Li> Jadon Sand as Finn, The Man Upstairs' young son in the live - action part of the film </Li> </Ul> <Li> Chris Pratt as Emmet Brickowski, an everyman and construction worker from Bricksburg </Li>
