While this is the first time we're actually seeing the volley of slaps, Isaac has talked about his rough day at work in the past — appearing on The Late Show when the film was released, he said: "I think it ended up being like 27 takes of Carrie just leaning in, and every time she'd hit a different spot in my face."
To Vanity Fair, he said: "She loved hitting me."
In other Star Wars news, this week Mark Hamill claimed that his character, Jedi Master Luke Skywalker, would have died in Episode 9 of the Star Wars franchise in George Lucas' version of the story.
Instead, Hamill's character died in Star Wars: The Last Jedi, which was written and directed by filmmaker Rian Johnson.
That movie, considered the eighth "episode" in the space series, hit theatres last December.
"I happen to know that George didn't kill Luke until the end of [Episode] 9, after he trained Leia," Hamill told IGN. "Which is another thread that was never played upon [in The Last Jedi]."
Johnson's film does not feature Skywalker training his sister, played by Fisher.
