I’m pretty sure Ahmed Best wore the suit for ROTS because he did an interview where he talked about a “dark and intriguing” scene starring Jar Jar that eventually got cut and hasn’t made it onto any DVD/BD releases yet.
Years ago I heard rumors of a scene where Jar Jar was killed by Clone Troopers in the Senate building. I even saw a clip that was probably fake, but since the whole movie looked fake I couldn’t tell 😉.
Nah, in the interview he said it was a scene where Palpatine thanked Jar Jar for putting him in greater power over the government. I’m kinda glad it was cut because the fact that Jar Jar promoted him in the first place is a big “fuck you” to the audience already.
