How to train your dragon in Northern Ireland is not without its challenges.

On the one hand, dragons are often big.

According to the film's producer David Cain.

"When they animate, they draw it to the convenient size they need," he told BBC News NI.

“But when you work in real space, a big dragon is a big dragon that takes up the space you need.”

How to train dragons is the first live action version of the movie in the movie animation series.

Directed by Dean Dublois, it tells the story of how humans and dragons make friends with each other, breaking the conflict between dragons and Vikings on the fictional Burke Island.

Berk was created at many locations in Northern Ireland, including Belfast, Dunseverick Castle on the North Coast and Torymore Forest.

For example, many visitors to the Belfast Titanic quarter will notice the castle of Viking Village, such as across the Titanic Studio.

Sampson and Goliath tower on the suit from a nearby shipyard, but the dragon was alone.

This incident undoubtedly impressed Gerard Butler, one of the movie's stars, namely Stoick, the leader of the Vikings.

"When people get into that energy and believe in the story after going through those scenes where they wear clothes, light up and catch fire in the hall."

BBC News NI talked about how to train Dragon producer David Cain, just before President Trump announced that tariffs could be applied to foreign-made films.

How to train your dragon starts with a successful animation trilogy in a movie made by Dreamworks.

And, according to David Cain, turning animated strikes into a live action movie, not just the size of a dragon, faces "various challenges".

He told BBC News NI: "You are trying to remake something loved and cherished and pay tribute to the original and make the original fans happy."

“At the same time, bring fresh and new things to the table.”

In Belfast, the work was filmed for several months at the Port of Belfast Studios and Titanic Studios in early 2024.

"We also built a large collection on the lot on the back," David Cain said.

“Obviously, a lot of our work takes place in the fabulous Burke Island and its villages, so we built a lot of sets outside for natural light and natural weather.”

Northern Ireland audiences will quickly recognize Dunseverick’s solid coastline, with the teenager playing hiccup played by Mason Thames and Astrid – played by Nico Parker – giving a heart-to-each speech in a key scene in the film.

Become friends with young dragons, toothless, challenge Vikings' certainty and conflict with dragons.

David Cain said Northern Ireland is "doing everything he can" to try to attract more big movies.

"I think you have talent in the crew right now," he said.

“What we know is the extra, these guys are so nice.

“You have phases now – I know Belfast Harbour is developing and there are other phases around.”

Six years after the end, it was clear that Game of Thrones left a lasting legacy.

David Cain believes that how to train dragons can also filter Northern Ireland into the world.

"Northern Ireland has always had a good reputation in the HBO of Thrones game that was filmed here, and there are many movies there," he said.

“We are a big movie and hopefully it will draw attention to the talent, location and stage that Northern Ireland offers.”
