As convenient as this is, just as I left this site and went on to YouTube, a new video by the Corridor Crew tackled this exact technology and used it to basically make movie characters explain their sequels.

The workflow was mainly using ComfyUI, with ElevenLabs AI for the voice cloning, and the results look pretty good if I say so myself.

I can genuinely see this as a potential to swap lines out from a character, like in TROS, to probably make Leia have more speaking roles, or something like that.
