Kit Harington On Playing Mark Wahlberg’s [SPOILER] In ‘The Family Plan 2’

Kit Harington is taking on sibling rivalry in The Family Plan 2, the Apple TV sequel to the 2023 action-comedy that introduced Mark Wahlberg as Dan Morgan, a former assassin trying to keep his family safe and his past behind him. This time, the drama hits even closer to home with the arrival of Dan’s long-lost brother, Finn, played by Harington.

The role marks a shift for the actor, who’s best known for brooding heroes. But this time around, he’s leaning into the action comedy chaos.

Kit Harington on joining ‘The Family Plan 2’

When the offer came in, Harington didn’t hesitate.

“It was great. I’d seen the first one and really loved it and knew what it was, knew what it was doing,” he said. “And it was a great family action comedy. And I love a movie where it knows exactly what it is, and it does it brilliantly. Joining it was pretty simple. They kind of, ‘Do you want to play a villain? Do you want to film in your hometown? Do you want to fight Mark Wahlberg?’ I was like, ‘Yes.’ Tick, tick, tick. So the main pull, in some ways, was playing a character I don’t often get offered, which is the baddie or the antagonist. And that I was like, ‘Yeah, why not? That sounds fun.’”

Harington’s character doesn’t just bring tension—he adds a whole new layer to the Morgan family dynamic. As Finn, he shows up with a personal history that Dan’s never been aware of, but that’s shaped both their lives.

“I think what the first film did well and what hopefully this one does is it mirrors a kind of family dysfunctionality, but in a way that’s very surmountable,” he explained. “And I guess I add to that by being this long-lost brother who Dan doesn’t realize he needs in his life, but the other guy, Finn, has been focused on his whole life. And there are parts of that story I’m sure families can relate to that kind of adds into that dysfunctional kind of mix that they did so well in the first one.”

Simon Cellan Jones knew Kit Harington would suprise people

Behind the scenes, director Simon Cellan Jones said he was confident audiences would see a new side of Harington—and not just because he’s playing the villain.

“Well, I think Kit had such good instincts for this,” Jones said. “I mean, I think a lot of people will be surprised to see him as a bad guy, but he plays it with real menace and danger. But he’s got a little wit to him, Kit. He’s just an instinctively funny guy. So I wouldn’t say his character is a comedic character, but he sort of contributes to the humor just by his presence.”

Adding to the appeal: Harington got to film major parts of the movie in London, where he grew up.

“Well, I think this movie’s been turned around quickly,” he said. “We filmed this in January, and so the Christmas lights weren’t taken down yet. So we got to use those, and now we are doing this junket just as they’ve been put back up. That’s quite fast. They’ve done well. I love London at Christmas. It’s part of my memory base growing up. I was raised in London. I think that for me, the three cities as a Westerner, anyway, New York, Paris, and London, and we do two of those in this movie.”

While the action and humor are big on-screen, Jones said the story still comes down to the familiar push-and-pull of family life—something that’s always evolving.

“Families, they just keep growing, don’t they?” he said. “Their relationships evolve. The love stays, but the fighting stays as well. So I think they’re always going to be interesting to watch.”
