Speaking out on the WDW Magic forum, famed Disney leaker WDW Pro explained that Lucasfilm has started a new deal with Hamill over his likeness.
The fan wrote: “According to sources, Disney is seeking to push forward with the same technology used to create movies such as The Lion King 2019 and The Jungle Book 2016, as well as human facial CGI seen in Rogue One, to begin work on an unnamed film that would be fully computer animated but presented as a live action film featuring human characters.
“The goal is to test the waters of creating computer animated films indistinguishable from live action, thus bypassing the need for actors (and actor salaries), as well as the need for proximity.”
They went on to add: “Lucasfilm inked a deal with Mark Hamill without much fanfare within the past 18 months which permits them to produce films featuring a CGI Luke Skywalker. I’m told that within that contract, Disney also is given the ability to use CGI faux reality Luke in future adaptations of Galaxy’s Edge.”
