The Finnish World War II film The Unknown Soldier has become the biggest-ever film in the country since modern records began in the 1970s after collecting more than $14 million USD at the box office.

The film has also had 860,000 admissions, becoming the second most-attended film in Finland after Titanic. 20,000 people also saw the film in Sweden on its opening weekend, another record for Finnish film.

Based on one of Finland’s most popular novels, The Unknown Soldier is the story of an infantry unit’s tour of duty that lasts for more than three years during the second world war.

The film is currently being adapted into a television series.

Box office records are not the only wins for the film, with The Unknown Soldier now holding a Guinness World Record for the most high-explosives detonated in a film take.

In one shot, the team used 64.8kg of high explosives with a TNT equivalent of 70.5kg.
