Presumably you have heard this voice adjustment. https://www.facebook.com/share/v/1Bp9Z3wbEj/
I haven’t! I don’t have facebook and clicking that link brings me to a locked page.
I’m familiar with a guy named Canadian Vader on YouTube as well - his style is, to cite the Beastie Boys, slower and lower in general. It’s a good impersonation, but I prefer the Golden performance of that scene.
I also haven’t been able to find anyone doing anything with “Prepare a boarding party” but that ended up being a non-issue because that scene is mostly cut in this Special Edition anyway.
