Well the film was first shown in English at the Cannes film festival, where it's reported that the audience laughed at the performance of the antagonist's audio dub, and the quality of some of the other supporting actors was also not great. Since the audio track had a poor reception it of course would be changed.
At some point a new dub was done for the upcoming USA theatrical release (which then never happened), and this is what's known as the re-dub.
