Who voices Robin/Dick Grayson in The Lego Batman Movie?

Michael Cera voices Robin, also known as Dick Grayson, in The Lego Batman Movie. His performance presents Robin as an enthusiastic, highly affectionate orphan whose optimism clashes humorously with Batman’s guarded personality.

The film, released in 2017, uses the familiar DC Comics origin in which Bruce Wayne adopts Dick Grayson after the boy loses his parents. This version of Robin is deliberately bright, talkative, and eager to become part of Batman’s family, giving Michael Cera a role built around rapid comic timing and innocent enthusiasm.

The Lego Batman Movie was the first theatrical spin-off from The Lego Movie and brought back Will Arnett as Batman. Cera’s Robin is not the same character as Ben Schwartz’s later voice role in other animated projects, and Michael Cera is not voicing Batman himself. The cast also includes Rosario Dawson as Batgirl, Zach Galifianakis as the Joker, and Ralph Fiennes as Alfred.
