The Rick and Morty voice actor change shocked the animation industry when Adult Swim officially recast its two lead roles. For the first six seasons, co-creator Justin Roiland voiced both the cynical genius Rick Sanchez and his anxious grandson Morty Smith. In January 2023, Warner Bros. Discovery and Adult Swim severed ties with Roiland following felony domestic violence charges and subsequent workplace misconduct allegations.
Rather than canceling the massive sci-fi hit, network executives launched a massive, secretive search for soundalikes. The transition materialized in Season 7, introducing Ian Cardoni as Rick Sanchez and Harry Belden as Morty Smith. This shift permanently altered the behind-the-scenes structure of the Warner Bros. Discovery property, separating the creative writing room from the vocal performance booth.
The Catalyst Behind the Recasting
The decision to change voices didn't stem from creative differences. In January 2023, public reports revealed that Justin Roiland had been charged with domestic violence offenses in Orange County, California. Though these charges were later dismissed in March 2023 due to insufficient evidence, additional allegations regarding inappropriate workplace behavior and online communications surfaced across multiple media outlets.
Adult Swim acted swiftly. The network terminated its overall deal with Roiland and removed him from his production duties across Rick and Morty and Solar Opposites. Because Roiland voiced the two anchor characters who drive almost every scene, the network faced a binary choice: end a multi-million-dollar franchise or find exact vocal matches to carry the torch. Producers opted for continuity, setting off a months-long global audition process involving thousands of voice actors and professional impressionists.
Finding the New Voices: Ian Cardoni and Harry Belden
Replicating voices that had evolved over a decade proved daunting. Roiland's delivery relied heavily on improvised stammering, manic energy, and specific register placements that he had refined since the show's 2006 animated short origins.
For Rick Sanchez, producers selected Ian Cardoni, an east coast actor with a theatrical background who possessed the natural gravel and cynical cadence required for the mad scientist. For Morty Smith, the network cast Harry Belden, an actor capable of hitting Morty's signature high-pitched panic and frantic vocal cracks.
Adult Swim kept the identities of the new actors under wraps throughout the entire production of Season 7, letting the premiere episode air without prior credit announcements. Viewers heard the new performances organically before learning who was behind the microphones.
- Ian Cardoni captures Rick's cold detachment and sharp acidic delivery without relying on digital audio manipulation.
- Harry Belden anchors Morty's nervous inflection, maintaining the vulnerable everyman dynamic essential to the show's comedic contrast.
- Jon Allen joined the ensemble as the new voice of recurring character Mr. Poopybutthole, replacing Roiland in that role as well.
How the Shift Impacted the Production Process
Beyond the audio booth, Roiland's exit fundamentally changed how Rick and Morty gets made. During the early seasons, Roiland recorded his lines alone, often from home, taking minimal direction and heavily improvising dialogue.
With Cardoni and Belden stepping in, the production returned to a traditional studio model. Co-creator Dan Harmon, showrunner Scott Marder, and voice director Coop Davis worked collaboratively with the new actors in professional recording booths. This structured approach allowed for tighter script adherence, cleaner vocal separation during fast-paced arguments, and more reliable production schedules.
Fans noticed that the dialogue pacing shifted slightly. Without raw solo improvisation driving every scene, the interactions between grandfather and grandson took on a sharper, more synchronized rhythm.
