An insider of the James Bond movie spills beans on a battle scene that has never been done before

He is known for his ice cream under pressure.

But James Bond is about to reveal hidden depths with scenes of underwater combat filmed at a depth of 16 feet below the surface of a frozen lake.

The actor Daniel Craig – in his latest appearance as suave superspy – has shot the most daring stunts of the franchise in Norway.

Underwater cameraman Kjetil C Astrup unveiled the details of the dramatic filming of Bond 25.

He told the Sunday Mirror, "This is probably the most extreme thing that Daniel and some of the other actors have ever done.

"This link is the jubilee, the 25th and probably the last film of Daniel – so it must be special.

"In Specter, they had scenes of Daniel in the water in Venice, but they never had scenes of submarine battles or comedians under the ice. We innovate. "

He said the waterfall was so dangerous that the emergency divers were waiting during the 1 ° C dive in Oslo.

These dramatic scenes are part of an offer from producers to ensure the success of the blockbuster after a series of setbacks.

Craig and other actors have been trained in dive pools for weeks before going abroad.

And Astrup said that he had spent weeks tying a platform to the ice, ready for filming.

He said: "The water is at a degree Celsius – you have to use special equipment otherwise your diving equipment freezes.

"An ice cube is formed around your breathing apparatus, blocking the air. We dive with electric heated vests and go straight into the heated pools when we ride.

"We had to introduce camera equipment, actors, a lot of people on the ice, with a ton of equipment. This is where it becomes dangerous.

The film has suffered many setbacks, including director Danny Boyle who resigned for reasons of creativity.

And the star Craig tore an ankle ligament during the first filming in Jamaica, interrupting production during his recovery.

Kjetil says that an injury during the cold underwater scenes would have been a disaster.

He said, "Under the ice, it's incredibly cold and very dangerous, and you're trapped. It's not easy to go out.

"It's hard to communicate, that's why we use absolutely professional people, the best actors – we have very little chance."

Craig and his co-stars even had a special diet in preparation, eating fatty foods such as salami, cheese, nuts and eggs.

Kjetil, who worked with Michael Fbadbender on The Snowman in 2017, added, "Filming through the ice is very special with light.

"It's unique to be under the ice and watch the sun go through this super-crystalline lake. People will be amazed. "
