“I LOVED CARRIE but she was so exasperating!” recalls Mark Hamill. “In many ways, she really was like a sister: she drove me nuts!” Hamill recounts stories “running around the Death Star, bumping heads and trading quips” with wry affection. There’s a wistful air to his recollections but he breaks into a hearty chuckle when speaking of their frequent sibling squabbles.

“She was so high maintenance! When George took us aside on Jedi and told us Princess Leia was my sister, I said, ‘Hey, does that make Luke royalty?’ Carrie immediately barked, ‘No!’ She was adamant that she be the only one. Like, ‘Okay, I’m just asking.’”

Fisher’s death in December last year left a hole in the Star Wars family, not to mention narrative issues for Episode IX. But with a different writer and director, even The Last Jedi has had to deal with its share of continuity problems. Hamill recalls his first reading of the script back in 2015 and a panicked call to Rian Johnson over what Hamill insists was a glaring inconsistency.

“There was something that happened at the end of The Force Awakens when I’m standing on the cliff,” he says. “I called Rian in a panic because it was all wrong. He said, ‘It’s okay, I spoke to J.J. and he’s taking that scene out.’ It just didn’t match up with what Rian had written.”

The Luke Johnson wrote into Episode VIII is not the man we remember from three decades earlier. His traditional garb traded in for a Jedi parka (“There are a lot of steps on Ahch-To; robes are impractical”), Luke now spends his days doing chores and living a hermit’s life. That’s not to say he’s given up his claims to royalty completely.

“Princes William and Harry visited the set one day,” Hamill recalls. “I said, ‘Look, my Father is Lord Vader, my Mother is Queen Amidala, my sister is Princess Leia. Doesn’t that make me royalty?’ William said, ‘Yes,’ but Harry wasn’t so sure. I was like, ‘Darn it! If I could have gotten both of them, I could have really rubbed Carrie’s nose in it.”
