Watching it again, I can see the resemblance to Shatner's voice. However, if it is him, he must've been instructed to speak with an unnatural faux-British accent and then was pitch-shifted down, because his voice is much lower than I've ever heard it before and it doesn't sound like whoever is doing is is trying to lower his voice.
Is there any way to maybe re-phase shift it so that we could all prove it once & for all? For instance, could the same technique used in phase shifting the 4% PAL speedup to NTSC be done here?
a thought. BTW, boba, the set looks awesome.
