My partner’s response on learning this factoid while we were in Japan: “I’m not short, I’m just a samurai!”

Rogue One had FX inserted versions of Tarkin and Leia, and Ep9 had existing footage of Carrie Fisher written in. It was pre GenAI, though, and more likely programmatically generated in the former case, and the latter was just pulled from the cutting room floor from Ep 7 and 8.
