 The UK dub is different from the American version.Many of the names are changed (for example, Johan and Peewit's names become John and William, respectively), and several Smurfs are called by the wrong names.The UK dub also gives The Smurfs almost the exact same voice (with the exceptions of Papa Smurf and Grumpy Smurf), unlike the US dub which gives The Smurfs more distinctive voices from one another.
