Horror movie fans can handle a lot.

But theres one line not even the most hardenedTerrifierfanatic can handle.

This is a horror movie, its definitely a horror movie.

Indy the good dog in Good Boy

He loves his person.

He would do anything to protect him and hes detecting that something is wrong.

After all, Leonberg and Fischer are a real-life couple, and Indy is their dog.

But it was the arrival of Indy that finally made the movie happen.

Not that Leonberg and Fischer didnt realize they had a born movie star living with them.

Indys always had a really intense thousand-yard star, Fischer says.

Hes always kind of given us a little bit of uncertainty.

There are bombs sniffing dogs that do a better job than any computer.

While the focus on Indy offers interesting storytelling possibilities, it also created challenges for the production.

So we had to get creative with getting the camera on Indys level.

For much of the movie, you would have characters off-camera just by the way they were normally framed.

That focus on animal heights alignsGood Boywith another movie withSteven Spielbergconnections,ET: The Extra-Terrestial.

Its about the world of children inET, and inGood Boy, its about the world of the dog.

Its almost like Indy becomes a silent film actor.

Unlike actual silent actors, however, Indy is a dog and has different motivations.

He continues, But there are huge advantages to that.

We had to build the production, which is both a limitation and an asset.

We built the production around Indys schedule, around the things he already naturally does.

You cant train a dog to fall asleep on command.

I think horror works best when its relatable, Leonberg continues.

We named the dog Indiana, laughs Fischer, quotingSean ConneryinIndiana Jones and the Last Crusade.

MaybeGood Boyisnt just a movie that doesnt put the dog in danger.

MaybeGood Boyis the movie that allows Indy to be the star he was always to be.
