The actor/stuntman ( Ray Park) who portayed Darth Maul can also be seen as "Toad" in the X-men movie,he has a very thick, youthful australian accent. so in episode 1 they dubbed over his small speaking part with a deeper more sinister sounding voice actor. he also portayed the Headless horseman in "Sleepy Hollow" where he had no speaking parts for obvious reasons.
