Crimson Maul’s deepfake work was very good, but it’s from a few years back already. I’ve been hoping that, with the advancements in AI, Crimson Maul or someone else would create a really clean version of the unmasking of Vader featuring Hayden Christensen. If there’s anyone out there with that capability, please consider taking on the project. Just about any Star Wars fan would be interested in seeing that, and the fan-editing community would be in your debt.
I could quite easily do the voice work for a scene like this, I think. I’d just need to get a Hayden voice clone, and use the tool that takes pre-existing voice work and basically applies the voice clone as a filter over it. So you end up with the exact same line delivery as Shaw, but in Hayden’s voice.
The only reason this method didn’t work when I tried it for the Kenobi flashback scene is because his voice was too entangled with the lightsaber noises. But this scene is perfectly quiet aside from the music, which would be easier to isolate.
