This is an interesting article in the New York Times about how Lucasfilm worked through the various issues involved in (SPOILER ALERT) using digitally recreated dead (Peter Cushing) and younger (Carrie Fisher) actors in Rogue One. I thought it was pretty cool to see this for a number of reasons, but one of them was that I wrote about this a few years back in Buyout (IndieBound | Amazon). One of the characters in that book is a movie director who exclusively does weird remakes of classic films using digital recreations of dead people.
Also recently there was news about Mark Zuckerberg using Morgan Freeman as the voice of his house AI. That too happens in Buyout, where the Kindred household AI has Ian McKellen's voice (as Gandalf) and his car persona is John Wayne. It's always fun to see science-fictional imaginings pop up so specifically in real life a few years later -- although I hope Buyout's central SF premise never comes to pass.
(I would be remiss if I did not now inform you that the Kindle version of Buyout is only $2.99, so, you know...)
