The original version of Disney’s Frozen was made in English.
Frozen was produced by Walt Disney Animation Studios for an English-speaking theatrical market, with the original cast recording dialogue and songs in English. Kristen Bell voiced Anna, Idina Menzel voiced Elsa, Jonathan Groff voiced Kristoff, Josh Gad voiced Olaf, and Santino Fontana voiced Hans.
Disney later created dubbed versions for release in many countries. The film’s songs were translated and recorded in numerous languages, which helped the story reach international audiences while preserving its musical structure.
The original-language version should not be confused with the language of a particular cinema release or home-video track. A screening in France, Germany, or Spain may use a local dub, but the source production’s original dialogue and lyrics are English.
