The Sing 2 voice cast brings together Hollywood A-listers, pop icons, and veteran comedians to power Illumination's hit musical sequel. Directed by Garth Jennings, the film shifts its scale from a local community theater to the neon-soaked stages of Redshore City. It requires its voice actors to balance high-energy comedic timing with emotionally demanding vocal performances.
Unlike traditional animated films where dialogue is recorded in total isolation, the production process for Sing 2 heavily integrated music recording sessions early on. This allowed animators to match lip movements and complex dance choreography directly to the actors' distinct vocal cadences. Below is a breakdown of the primary cast members, the characters they play, and the production details behind their performances.
Main Characters and Voice Actors
Buster Moon Voiced by Matthew McConaughey
Matthew McConaughey returns as Buster Moon, the perpetually optimistic koala who refuses to let setbacks stop his theatrical dreams. McConaughey's easygoing Southern drawl grounds the character, providing a steady anchor for the sprawling ensemble. In this sequel, Buster faces much higher stakes as he pitches a sci-fi musical to a ruthless media mogul. McConaughey leans into that persistent confidence, ensuring Buster remains charming rather than exhausting.
Rosita Voiced by Reese Witherspoon
Reese Witherspoon voices Rosita, the hardworking mother pig who handles dozens of piglets at home while harboring massive artistic ambitions. In Sing 2, Rosita's character arc expands significantly, particularly during a vertigo-inducing aerial stunt sequence that forces her to confront her fears. Witherspoon performs her own vocals for the film's musical numbers, bringing a genuine sense of vulnerability and breakthrough to her character's transformation.
Johnny Voiced by Taron Egerton
Taron Egerton reprises his role as Johnny, the gentle giant gorilla trying to break free from his criminal family legacy. Egerton's vocal performance drives much of the film's emotional weight, especially during scenes where Johnny struggles to master contemporary dance choreography under a harsh instructor. Egerton sings several major tracks in the film, including high-octane covers that showcase his extensive vocal range.
Ash Voiced by Scarlett Johansson
Scarlett Johansson plays Ash, the rock-and-roll porcupine who has evolved from a backup singer into a confident solo artist. Johansson's raspy, grounded delivery gives Ash her signature edge. In the sequel, Ash acts as a crucial mentor to a reclusive rock legend, requiring Johansson to convey both quiet empathy and fierce independence through her vocal work alone.
The Antagonists and New Additions
Jimmy Crystal Voiced by Bobby Cannavale
Bobby Cannavale joins the cast as Jimmy Crystal, an intimidating arctic wolf mogul who rules the entertainment industry with an iron fist. Cannavale brings a volatile, aggressive energy to the role, shifting on a dime from smooth corporate charm to terrifying fury. His performance provides the primary dramatic tension that forces Buster's crew into high-stakes hiding.
Clay Calloway Voiced by Bono
U2 frontman Bono steps into animation voicing Clay Calloway, a legendary rock star lion who has lived as a hermit for fifteen years following personal tragedy. Bono's raspy, world-weary speaking voice and iconic singing style bring an authentic layer of rock history to the character. His scenes with Scarlett Johansson form the emotional core of the film's third act.
Porsha Crystal Voiced by Halsey
Pop star Halsey voices Porsha Crystal, Jimmy's spoiled yet remarkably talented daughter who muscles her way into Buster's production. Halsey captures the theatrical over-enthusiasm and teenage insecurity of the character, delivering standout renditions of pop hits during the audition and rehearsal sequences.
Behind-the-Scenes Production Challenges
Recording for an animated musical requires a unique workflow that differs from standard voiceover work. The cast recorded their lines across various studios worldwide, often years before the final lighting and rendering were completed.
- Musical Synchronization: Because the plot revolves around preparing a massive stage show, actors had to record their singing tracks before animators finalized the character movements. This ensured that foot-tapping, head-banging, and breath control aligned naturally with the on-screen choreography.
- Ensemble Chemistry: Even though performers like Tori Kelly (Meena) and Nick Kroll (Gunter) often recorded separately, director Garth Jennings used scratch tracks and read-through recordings to help actors react as if they were standing face-to-face in a recording booth.
- Acoustic Realism: Sound designers layered specific acoustic profiles for different venues in the film, ranging from cramped basement auditions to the echoing expanse of the Crystal Tower Theater.
