Solo: A Star Wars Story was always going to create waves in the Star Wars community, after all, how could you possible recast a role like Han Solo and not feature Harrison Ford?
Well, thanks to Deepfakes – an AI-based deepfake technique – Solo actor, Alden Ehrenreich, was replaced with Ford's famous mug. The footage comes from YouTuber derpfakes, who rose to prominence in the community around the machine learning-based tool by using it to substitute actor (and human meme) Nicolas Cage into famous film scenes instead of creating creepy, homemade fake celebrity porn.
Let's totally honest here: derpfakes’ clips, while no doubt technically impressive, show how far this technology still has to go to make it seem more legit. Things like facial expressions and lip movements just don't match up, and Ford's face just looks kind of weirdly floating over Ehrenreich, especially in the earlier, more brightly lit scenes. The later shots from Lando's more dimly lit card game fare far better – possibly due to the farther framing of Han's face and darker lighting, but it's still not a great substitute for the real actor.
Looks like Star Wars fans will just have to learn to deal with changes to the franchise for now.
