When the all-star voice cast of the 2019 animated film The Addams Family reunited for a spooky road trip sequel, Chloë Grace Moretz didn’t need to look any further than her own family to get into the spirit of things.

“We loved going on road trips all the time,” recalls the former child star who reprises her role of Wednesday Addams in The Addams Family 2. “Growing up in Georgia we were constantly driving to Florida because it was the closest beaches. We took so many family road trips down to Key West.”

In the new movie – starring Charlize Theron as Morticia, Oscar Isaac as Gomez, Javon Walton as Pugsley and Snoop Dogg as Cousin It – we find Morticia and Gomez distraught that their children are growing up, skipping family dinners, and totally consumed with “scream time”.

To reclaim their bond, the clan decide to cram Wednesday, Pugsley, Uncle Fester and the crew into their haunted camper and hit the road for one last miserable family vacation. Their adventure across America takes them out of their element and into hilarious run-ins with their iconic Cousin It, as well as many new kooky characters.

If Moretz’s own childhood road trips weren’t quite so dramatic, then they were memorable for other reasons.

“I would always get car-sick, so I think our own family horror stories landed in the world of vomit. This is predominantly where the horrors of Moretz’ road trips lie!” she tells STACK.

“As an adult, I’ve grown to love road trips even more so, and make them often. I actually did a 4,400-mile road trip from Charleston all the way up to Wyoming, to Portland and then all the way down the coast back to LA. So I do love a good road trip and the crazy things that occur while you are on them – and a little bit of cabin fever that happens along the way,” she says.

“So I think it’s really nice to be able to go on this road trip with the Addams family. I think we get to see so much more of the characters now that we already know them and have met them. We really get to see them interact on a personal level in a very cinematic way.

“It really felt like a full film with intense storylines – and some heavy subject matter with a family. It also deals with growing up and some of those coming-of-age storylines, and they navigate it in a really wonderful way. I think people will enjoy going on this discovery and this road trip with them. There’s some pretty fun sights and we get to see a whole lot of Cousin It, who is a fan-favourite from the first one.”

One of the fun things in The Addams Family 2 is Wednesday’s relationship with little brother Pugsley, constantly devising new ways to kill him.

“I think my favourite scene is the Niagara Falls sequence with the voodoo doll,” she laughs. “It’s just so funny. There’s something about the voodoo doll gag that always gets me, and even the scene in the RV when she’s wrenching Pugsley and he’s screaming to his mom and Morticia is completely ignoring him.

“I can’t say that if I had a voodoo doll that I wouldn’t use it on my brothers,” she teases.

Just seven years old when she won her breakout role in the 2005 remake of The Amityville Horror, Moretz relocated to LA with her mother and brothers, going on to star in 500 Days of Summer, Dark Shadows, Hugo and Kick-Ass.

Her mum Teri, a former nurse, has helped guide her career along with her elder brother Trevor, who also serves as her acting coach.

Unafraid to take on dark roles, she played a prostitute alongside Denzel Washington in The Equalizer, a high school killer in Dark Places, and a 200-year-old vampire in Let Me In.

The first Addams Family cartoon appeared in 1938 in The New Yorker, spawning video games, comic books, a musical, popular TV sitcom and several films.

Ask Moretz if she has any theories on the spooky family’s longevity and she’s clearly given it some thought: “I think the thing that audiences have always fallen in love with about them is the fact that this is a family that is so protective of one another. Their family bond is so intense that nothing can really break them. They can be whoever they want to be, they can be kooky, they can be weird, and it’s unabashed – and the family support them no matter what.

“They allow each other to be their weird, odd selves and they don’t criticise each other for their eccentricities. So it is something that I have always been interested in, but from when I was much younger, because of that.

“And with them being on the darker, creepier and more macabre side of life, it allows people to be welcomed into that world without feeling scared. Because, at the end of the day, it’s just funny and there is so much satire involved. But I do think that it’s the family bond that has allowed it to stand the test of time. Everyone has felt a little odd at some time, so I think it’s a place that you can go to be odd and not feel like you are being ostracised for it,” she says.
