Fans from 15 countries head to Prague for Nolan's 'The Odyssey' on 70 mm IMAX

With Christopher Nolan's highly anticipated "The Odyssey" recording impressive sales around the globe, thousands of Europeans have used it as a new and unexpected reason to visit Prague.

The Czech capital has a movie theatre that's among the few dozen in the world equipped with the coveted 70 mm IMAX screen to watch the first feature made entirely with IMAX film cameras.

"It completely changed my experience about the movie," said Nicolas Walak from Poland, who also saw the movie before on a normal screen before viewing it in Prague. "Everything was great. It was a great movie."

Czech cinema adapts to meet demand for rare IMAX format

There are only 41 70 mm IMAX screens worldwide, with most in North America. Montpellier in France and the Belgian capital, Brussels, are the only other two in the European Union countries. Britain has another three.

To meet massive demand, the Czech branch of the Cinema City offers four to five screenings a day, one starting after midnight, and the majority are sold out.

Film fans from about 15 European countries, from Scandinavia to Spain, have been coming to watch "The Odyssey" in Prague, Cinema City said. Their number reached 22,000 by Monday, it said.

The 70 mm IMAX film presentation is Nolan's preferred format. The Oscar-winning filmmaker calls it the "best possible experience."

Moviegoers travel up to three days to Prague

Daniel Jung drove with his two teenage sons, Felix and Leo, for three days from Norway through Denmark and Germany "just to see this movie. Tomorrow, we're going back."

Leo was in touch with Cinema City by email half a year before the July 16 premiere and followed the cinema operator on Instagram. He managed to book the tickets immediately after they became available.

"We were in the 11th row, right in the middle. We had the very best seats," Leo said, calling the effort "absolutely worth it."

"It's just so big. We come from Norway, the screens we have are much smaller," he said. "Now, we watched it in this huge format. I will always remember this experience."

Felix said they had a good time on the way, visiting some places in Germany, but it would be worth it even if they just drove straight there.

Few IMAX left because of costs and other challenges

Due to the cost and other challenges, productions made using large format film are rare. The IMAX cameras are heavy, and new versions with reduced noise had to be developed to be usable for making "The Odyssey."

The film print sent to theatres is so big — weighing some 300 kilograms (661 pounds) and 18 kilometres (11 miles) long — that it has to be delivered to theatres in parts. The movie and the projector have to be in a climatized room, and the projectionists need to be approved by IMAX for the job.

As movie theatres around the globe were acquiring digital IMAX equipment around 2008, the Cinema City decided not to get rid of the original analogue projector in Prague. It was placed in a corner for three years until 2012 to screen Nolan's "The Dark Knight Rises."

It was used to show several others, including Nolan's "Interstellar" in 2014 and "Oppenheimer" three years ago.

"We're really grateful to him for that," projectionist Tomáš Vyšinský said about his predecessor who saved the equipment.
