ANECDOTES
- As Anthony Kavanagh comes from Quebec, dubbed Ray in the European French dub as well as the Quebec French version.
- The Castilian title "Tiana y el Sapo" (Tiana and the Frog) was unpopular in Spain because it wasn’t faithful to the original.
- The Princess and the Frog is the first Disney movie to be dubbed in Estonian, Latvian and Lithuanian.
- The Indonesian and Malay dubbings are TV dubs, never released on VHS/DVD/BLU-RAYs.
- The Albanian and Persian dubs aren't officially Disney, they're made by small independant studios.
