The Long siblings take EW behind-the-scenes of their canine-themed body horror segment, “Fur Babies.”

Surgical tools and jaw bones lay scattered on a stainless steel medical tray.

“Basically, it’s about this woman who runs a doggy daycare service.

“I think a lot of people know a version of that person,” Justin adds.

“Sometimes they even say it out loud: ‘I love dogs more than people.’

They are usually pretty positive and chipper, but there’s always something a little bit off.

We liked the idea of looking at that and pushing it to its extreme.”

“We definitely thought about it,” Justin says.

We thought ,really, but I guess that applies toTusk, as well.

“For sure,” Justin agrees.

“And we both love creature effects.

We grew up in the ’80s, so that in-camera stuff really appeals to us.

It’s been fun getting to incorporate that and creating something hopefully different in horror.

The brothers credit veteranV/H/Sset and costume designer Patrick Magee for creating the humanoid canines.

“It was funny explaining the story to him,” Justin remembers of his first conversations with Magee.

“He didn’t bat an eye.

I love that process.

I love seeing it come to life.

And now, I get to have a different perspective on it.”

“But they seem really eager.

Our dogs just couldn’t be more game.”

“He was the friendliest, most collaborative guy who wants everybody to be a part of the process.

I can’t say enough about Justin Long.

He’s incredible.”

“He asked, ‘What’s all that noise in the background?’

And I was like, ‘Oh, I’m on set doing aV/H/Smovie.”

“You’re a Scream King,” Christian declares when the conversation turns towards Justin’s genre credentials.

“Or maybe a Scream Prince.”

“I don’t know how regal I am,” Justin jokes.

“Am I old enough to be a king?”

Justin relents with assurances that he is indeed old enough at the age of 46 to be horror royalty.

“I just love working, and I love the genre.

“We’ve been talking a lot about how close those two really live,” he adds.

“It’s a similar formula, almost mathematical.”

“It’s all timing,” Christian agrees.

People say, ‘How do you work with your brother?’

Some are surprised by how easily we work together.

To me, it’s like the easiest person to work with because we think so similarly.

It’s like I trust myself.

We don’t really have conflict.

Now I feel like we’re jinxing things.”

“That’s true,” Christian says.

“We still have a big afternoon.”
