The Lego Batman Movie cast features a surprisingly vast ensemble of comedy stars, blockbuster actors, and pop icons who brought Gotham City to life. Directed by Chris McKay, the film took the self-serious mythos of the Dark Knight and spun it into an emotional, brick-built comedy packed with dense lore. Understanding who voiced these plastic counterparts reveals how a children's animation project managed to cram in decades of cinematic history.
At its core, the movie balances a surprisingly heartfelt story about family and isolation with rapid-fire jokes. Will Arnett returned to voice the titular hero after his scene-stealing breakout in The Lego Movie, anchoring a lineup that includes major Hollywood talent playing classic villains, heroes, and unexpected deep-cut characters from across pop culture.
The Main Cast and Their Roles
The primary voice cast forms the emotional and comedic backbone of the story. Each actor leans hard into the satirical nature of their characters while keeping the underlying stakes grounded.
- Will Arnett as Bruce Wayne / Batman: Arnett brings his signature gravelly, overly dramatic baritone to a hero terrified of emotional attachment. His Batman spends his nights fighting crime and his lonely days eating lobster thermidor alone in the Batcave.
- Michael Cera as Dick Grayson / Robin: Cera adopts an aggressively enthusiastic, high-pitched persona for the orphan whom Bruce accidentally adopts. His oversized glasses and tearaway costume highlight the absurdity of a kid tagging along with a brooding vigilante.
- Rosario Dawson as Barbara Gordon / Batgirl: Dawson plays Gotham's newly elected police commissioner. She wants to transition the city away from relying on a reckless vigilante and toward structured, legal law enforcement, eventually donning the mask herself.
- Zach Galifianakis as The Joker: Galifianakis portrays the Clown Prince of Crime not as a terrifying anarchist, but as a needy ex-boyfriend desperate for Batman to acknowledge that he is his greatest enemy.
- Ralph Fiennes as Alfred Pennyworth: Fiennes gives the loyal butler a dry, deadpan edge. He acts as both a father figure and an exasperated life coach who forces Bruce to confront his fear of family.
- Mariah Carey as Mayor McCaskill: The pop superstar voices Gotham's upbeat mayor, who happily participates in city events and relies heavily on police leadership to keep the peace.
The Rogues Gallery and Supporting Voices
Beyond the central dynamic between Batman and the Joker, Gotham's broader underworld features a lineup of comedic actors voicing iconic villains and side characters.
- Jenny Slate as Dr. Harleen Quinzel / Harley Quinn: Slate handles the chaotic sidekick duties with an energetic, fast-talking delivery.
- Billy Dee Williams as Harvey Dent / Two-Face: Williams finally gets to voice the villainous district attorney, a playful nod to his portrayal of Harvey Dent in Tim Burton's 1989 Batman film.
- Conan O'Brien as Edward Nygma / The Riddler: The late-night host brings his distinct cadence to the puzzle-obsessed villain.
- Jason Mantzoukas as Dr. Jonathan Crane / Scarecrow: Mantzoukas channels manic intensity into the master of fear.
- Doug Benson as Bane: Benson plays a caricature of Tom Hardy’s muffled Bane voice from The Dark Knight Rises, complete with constant jokes about his size.
- Zoe Kravitz as Selina Kyle / Catwoman: Kravitz steps into the feline anti-hero role well before playing Catwoman in live-action in The Batman (2022).
- Kate Micucci as Basil Karlo / Clayface and Riki Lindhome as Pamela Isley / Poison Ivy round out the primary villain ensemble as members of the Joker's massive coordinated attack force.
Non-DC and Franchise Crossovers
The film expands its universe by raiding the vault of global pop culture intellectual property. The Phantom Zone acts as a cosmic maximum-security prison holding villains from entirely different studio franchises, leading to bizarre vocal performances.
- Eddie Izzard as Voldemort: The British comedian voices the primary antagonist of the Harry Potter series, who frequently interacts with other classic literary monsters.
- Seth Green as King Kong: Green lends his voice to the giant ape, integrating classic monster-movie history into the Lego multiverse.
- Jemaine Clement as Sauron: The Flight of the Conchords star voices the Dark Lord of Mordor, complete with a booming, theatrical menace.
- Ellie Kemper as Phyllis: Kemper voices the polite, gatekeeping monster who manages the intake desk of the Phantom Zone.
Justice League Cameos and Tech Castings
Batman's relationship with the rest of the superhero community is a major source of comedy, particularly when he is left off guest lists for anniversary parties.
- Channing Tatum as Clark Kent / Superman: Tatum reprises his upbeat, eager interpretation of the Man of Steel from The Lego Movie.
- Jonah Hill as Hal Jordan / Green Lantern: Hill returns to play the insecure, attention-seeking ring-wielder.
- Adam DeVine as Barry Allen / The Flash: DeVine brings a hyperactive, fast-talking energy to the speedster.
- Siri as the Batcomputer: Credited simply as 'Puter, Apple's digital assistant serves as the sarcastic artificial intelligence managing Batman's fortress and vehicles.
