There is probably a time in the not-too-distant future where the presence of deceased actors in movies will become commonplace, or at least where actors don’t have to be de-aged because their younger selves were digitally scanned and can show up in movies.
For Mark Hamill, at least, he’s all in on his digital resurrection.
While people have mixed feelings about that scene overall, to me at least, it looked more real than either of the digital recreations in Rogue One.
That uncanny valley is still vast, but each new advancement makes it just a little bit smaller.
