The Cast That Brought Big Hero 6 to Life

At the heart of Big Hero 6’s success is a stellar voice cast whose talents transcended timing and personality to deliver unforgettable performances.

Voice Actors & Characters

• Baymax — voiced by Batman voice legend Tom Holland (yes, that’s right—Swiss actor Tom Holland, before his MCU rise, skilled in vocal pantomime) brought softness, empathy, and childlike wonder to the robot-nurse who quickly became Pixar’s most endearing non-human protagonist.
  
• Hiro Hamada — Chris Evans, best known for Captain America, lent intensity and emotional depth, grounding the young inventor’s journey from quiet grief to confident hero.
  
• Fairly — Michelle Yeoh infused calm wisdom and quiet strength, offering emotional anchoring to the team with her measured yet compassionate tone.
  
• Fred — Earl Ciuri brought humor and warmth, capturing the bubbly schoolboy study group’s heart with perfect comedic timing.
  
• In nationality and background, this diverse casting wasn’t just diverse—it was deliberate, helping broaden the story’s global appeal.*

• Designers sought tonal versatility at first. Various actors read for Hiro and Baymax, but the voice with just the right mix of sincerity and subtle humor emerged through trial and voice recording sessions.
  
• Chris Evans nearly didn’t get the role!-he was considered for Hiro but had to prove he could embody the character’s humility and growth. Pitch recordings of his softer, more reflective performances made the producers take notice.
  
• Baymax’s signature “Hiii” was recorded over seven takes before capturing perfect emotional expression—every inflection was refined to sound genuine and caring.
  
• Earl Ciuri’s Fred was originally voiced in a test tape as a deeper baritone, but director Pete Docter loved the youthful teasing quality, pushing for that lighter tone that fans adore.
  
• Bonus Insight: The voice cast collaborated closely with animators during post-production, giving real-time feedback to perfect lip-syncing and emotional facial expressions, showing how voice and animation evolved as one.
