Will Ferrell played both Lord Business and the live-action father in The Lego Movie. The dual casting is deliberate: Lord Business is the film’s tyrannical Lego villain, while the live-action character—usually called the Man Upstairs—is the father of a boy named Finn.
Inside the Lego world, Lord Business is President Business, head of the Octan Corporation and ruler of the Lego universe. He plans to use the Kragle, a weapon based on Krazy Glue, to freeze every object permanently in what he considers perfect order.
The live-action scenes reveal that Finn’s father is also a Lego collector who dislikes his son’s improvised creations. Finn models Lord Business partly on him, turning the villain into a playful metaphor for an adult trying to control a child’s imagination.
Ferrell therefore portrays two versions of the same thematic conflict: an authoritarian figure in the Lego story and the real-world parent whose strictness inspires him. Chris Pratt voices Emmet, while Elizabeth Banks voices Wyldstyle and Will Arnett voices Batman.
