And the British actor who plays Jon Snow in the hit HBO series has said he couldn't help shedding a tear following the last ever script read-through with fellow cast members.
"I'm really emotional about it," he said on "The One Show," which aired on BBC One in the United Kingdom on Friday night. "I cried at the end."
It's bad news for fans who think his emotional reaction may hint at what happens to his character, however.
But Harington himself said he was more upset about the ending of a show on which he's worked for the last eight years.
"It's been an institution longer than any other institution I've been in, school, drama school, anything," he said. "I get a bit weepy thinking about it. It's gonna be a strange sort of year saying goodbye to everyone."
