As much hate as the character of Jar Jar Binks received in Star Wars: Episode 1 The Phantom Menace, there has been a recent outpouring of fans who would like to see him turn to the dark side.
With that in mind, Youtube user Jamie Stangroom, who runs a channel called "These Are The Actors You're Looking For", recently spoke to Jar Jar actor Ahmed Best about what a Sith version of Jar Jar might sound like.
While he did a darker version first, theorizing that the original voice was just a cover all along, I have to admit the more Jar Jar sounding voice he did after that is more threatening for some reason. Maybe it's because when he speaks you see the character in your mind that couldn't harm a fly, but with all this anger and hatred behind it. A little unsettling.
