From The Hollywood Reporter:
“[…] [Samuel L.] Jackson is digitally de-aged for Captain Marvel, which takes place in 1995. He first was introduced to CGI-heavy filmmaking thanks on 1999’s Star Wars: Episode I — The Phantom Menace in which he played Jedi master Mace Windu. Director George Lucas told him the key to interacting with things that weren’t really there was knowing what questions to ask.
“He said, ‘You need to know how big is it, where is it, how fast is it,’ ” recalls Jackson. “And I was, like, ‘Okay. How big is it?’ He said, ‘Uh, about an SUV.’ ‘How fast is it?’ ‘Mm, 40 miles an hour.’ ‘And where is it?’ ‘Coming straight at you.’ ”
Jackson says it made him feel like a kid in his room, fighting imaginary bad guys, and that Lucas noted that the more moves he showed off, the more things the animators would create to match his lightsaber fighting.
In the years since, technology has made it possible for actors to live on in movies after their deaths. 2016’s Rogue One: A Star Wars Story resurrected Peter Cushing’s Grand Moff Tarkin more than 20 years after the actor’s death, while Star Wars: Episode IX will utilize unused footage of the late Carrie Fisher to make her General Leia a character in the film.
How would Jackson feel about being digitally re-created someday?
“Awesome,” he says.”
