While on set for the Knights Templar drama Knightfall, Mark Hamill discusses Episode IX security with Entertainment Weekly:
“They’re going to fly [the rewrites] over with somebody from the company,” Hamill said. “They’re going to come and give it to me and wait for me to read it before I give it back. So no pressure! You can’t even keep it overnight. But that’s the way it is now.”
He reveals that he has done about a week of filming for the next Star Wars, and will head back between his Knightfall schedule. He also has a “very high profile” non-Star Wars voiceover project coming up that hasn’t been announced yet.
Knightfall season 2 doesn’t have a premiere date yet, but Episode IX will be out December 20, 2019.
