Yeah, Mocata is right. A nice touch for an easter egg, but really didn’t amount to anything.
It would be cool to hear Guinness’ voice being used again in the future. That voice AI seems to be getting better, and they likely have his back catalogue of vast work outside of Star Wars to pull from.
Maybe its is just cheaper and easier to get Ewan to do it, as daveybjones999 posted? Or one of the guys who played Obi-Wan in the animated series? The actor Jamie Costa seems to be highly rated for it too.
I do get what you mean by Kenobi feeling more like a Prequel than a bridge between the 2 trilogies, Emre. The fan service didn’t help on that, nor did Ewan doing an impression of the work he did 20 years ago, instead of bridging that work towards Alec Guinness’ Kenobi. But I doubt that was a thing they were even aiming to achieve.
