'The Electric State' voice cast: Who voices the robots in Millie Bobby Brown's Netflix movie? (2025)

Along the way, she discovers there is more to humanity’s war with the robots than appears on the surface.

Eventually, Michelle and Keats discover a commune of robots living peacefully in an abandoned mall. This is where a cast of star-studded actors with distorted voices come in. Read on to learn about who plays the robots in The Electric State voice cast.

2. Herman Voice Actor in The Electric State: Anthony Mackie

   

   The voice of Herm, the robot sidekick to Chris Pratt, is less obvious, thanks to even more voice distortion.

In an interview for the movie’s production notes, star Chris Pratt said Mackie’s dialogue was added in post. “During production, a lot of the banter between Keats and Herman was a combination of riffing with Joe Russo and Marty [Martin Klebba], the mo-cap actor behind Herman,” Pratt said.

   When it comes to the little catchphrases uttered by the Cosmo bot that hosts Christopher’s consciousness, those lines were read by Firefly star Alan Tudyk.

In an interview for The Electric State production notes, co-director Joe Russo praised Tudyk for giving Cosmo “just the right mix of warmth and limitation.”
