We are at the old Haeggernaes windmill, which is beautifully located on the seafront outside Nyhavn in Sandviken.

At least 100 man moved in for a day here to shoot key scenes for the film adaptation of Jo Nesbo 'The Snowman', which has six shooting days in the Bergen area. Meanwhile, another team is busy with filming scenes at the train station.

It is exceptionally crowdie on the 11th floor in the Hegg Erne Road. The photographer Dion Beebe ( "Memoirs of a Geisha," "Chicago") ensures that the light is good enough to film in the small office there.

Swedish director Thomas Alfredson ensures that the two actors in the scene, Michael Fassbender and Adrian Dunbar, know where they stand and move. Outside the sun bathes in the bay, but this time the filmmakers are not interested in capturing the picturesque of Bergen.

It's the Saturday, when Val Kilmer and Toby Jones do all the scenes they did not get done on top of Ulriken on Tuesday, when the wind was up in 25 meters per second. There are three lovely weather Saturdays, windless and plenty of sun.

- It was really windy Tuesday. Fortunately, we have the opportunity to do it over again. Otherwise I am very happy with the footage we've done here in Bergen. Some of the scenes we shot out at sea on Thursday. Fantastic. Everything goes according to plan, - says Thomas Alfredson to BT. He’s calm and exceptionally prepared as usual.

Michael Fassbender is a megafan of Alfredson. He's ready to spend several months in Norway for just filming 'The Snowman':

- It's much better to work on location than in studios, even if it's freezing cold here in Bergen now. One of the privileges of being an actor is that you can see places that many others can’t get to, - says Fassbender, who has never been to Bergen.

He chats with staff between takes and seems very relaxed. In few days' time he's heading to Los Angeles to take on the tux and attend the Oscars Sunday. He is known as nominations for Best Actor, for the title role in "Steve Jobs."

Two weeks ago, he had to be at the BAFTA awards in London. Such interruptions in a busy filming schedule do not scare the actor.

- Luxury Problems, darling, - says he, laughing.

- Of course it's not ideal to get such breaks, because I like to be concentrated and focused when I play a movie. But I travel very comfortably. I can sleep anywhere, even here on the concrete floor. I relate to the realities of this industry and do what I must do, - he says.

Producer Robyn Slovo, who also worked with Alfredson on John le Carre-film adaptation "The Mole" (2011), could not have been more happy with the footage of Bergen and in Norway in general.

- There are some amazing locations here. I've been over to Bergen several times with Thomas Alfredson and the screenwriter, because we wanted to see the places that Nesbo described in the book. It was always our plan to film in Bergen and Oslo - long before Norway introduced an incentive scheme for foreign film productions. There wasn’t ever any doubts about where to film, really, - says Slovo.

She says the Norwegian nature has given the film almost more than they had hoped for.

- Seeing the images from film you can say that it’s almost better than the reality. Norway will be Norway. Until now, the filming went as planned - including cooperation between the UK and Norwegian staff members, - says Slovo.

'The Snowman' will soon go directly to Rjukan, on Tuesday, when Bergen filming will be over. There they’ll stay for 10 - 12 days. Then the new shooting in Oslo that will last to the end (around the Easter time).
