Heavy Water War: Les soldats de l'ombre

This is a miniseries about the German efforts to create the first nuclear bomb as well as the Allied effort to put a stop to it. Much of the film is set in Norway, as it was the center for Nazi deuterium production. Because of this, the series is in Norwegian, English and German (with a tiny bit of French). While it might not sound that interesting, it is--provided you are patient and give the programs a chance. My only reservations are minor. First, although it's stylish, the shaky cam is a STUPID idea and I have no idea why it's used throughout the show. I watched it on a very large screen TV and it practically induced motion sickness. Second, the CGI of the B-17s was rather poor. Eight year old episodes of "Dogfights" look better and more realistic. Still, with excellent acting, an engaging script and a nice history lesson, it's well worth seeing.

By the way, some of what occurs in the show can also be seen in the excellent Kirk Douglas film "The Heroes of Telemark"--and is mostly covered in episode 6 of the series.

This decade or so, Norway has created several series depicting life and events during WW II in Norway, under German annexation, but still different way than in e.g. Central or Eastern Europe. But still, people had to make hard choices, and very often you were between rock and hard place, trying to see/predict a bigger picture and "sniff" potential outcomes. Kampen om tungtvannet gives a broad overview, through different angles and participants, of a successful, yet controversial operation (thus, in my opinion, the UK title The Saboteurs is not felicitous), with many real episodes and characters, performed by good character actors (more as a team, no one really sticks out unnecessarily). It is also to my liking that characters of different nationals were played by respective representatives, so different languages heard are always correct and without accent. Well, the run of scenes is not always smooth, some of them are excessive and tensions are sometimes fading, but still - this series is worth watching, at least for Northern Europeans interested in the events during WW II not commonly known.

Receiving great reviews and being a success among the public, setting the new record for drama series when it premiered on national TV network in Norway on January 4, 2015, winning the live audience of about 1.2 million viewers on Sunday night (about 24% of the Norwegian population was watching the season premiere), the Norwegian TV mini-series Kampen om Tungtvannet (original title) or The Heavy Water War: Stopping Hitler's Atomic Bomb (in English) depicts a true story of World War II. Narrated in three angles the Norwegian production of 6 episodes follows the trajectory of the Nazi nuclear program, the fight of the Allies to stop them and the management of Norsk Hydro, the company that owns the heavy water plant, a key substance for the German plans.

The TV mini-series begins slowly, developing the characters and their dilemmas and also exploring the reasons Allies and Nazis fight for the heavy water. Why it was so important and where it would be possible to get it? Over the first episodes this whole plot is made clear.

The Nazi research program is shown through the eyes of Werner Heisenberg (played by Christoph Bach, known for Shirley: Visions of Reality - 2013), German scientist who in 1933 won the Nobel Prize in Physics for his contribution in quantum mechanics. Heisenberg devoted his life to science, abdicating social and family life. In 1939 he began working for the German government, conducting the research for the development of nuclear energy. He sees the atomic bomb as a nuisance, but a necessary means for the development of science. The war would be at the service of science.

The Norwegian scientist and professor Leif Tronstad (played by Espen Kloumann Høiner, known for Reprise - 2006) was one of those responsible for the construction of the chemical factory Norsk Hydro, in the Vemork plant on the outskirts of the town of Rjukan in Norway. By joining the Allies in England, he was essential to prevent the success of the Nazi plans, since he was a member of the Norwegian Resistance and still stayed in touch with them. He also was aware of the building plan and the site procedures. To Tronstad the lives of employees and other inhabitants of the area should be preserved in the conflict.

The director of Norsk Hydro, Bjørn Henriksen (played by Dennis Storhøi, known for Zwei Leben - Two Lives - 2012), runs the facility in Rjukan, unique in the world to produce heavy water. As it was a byproduct of fertilizer production, its production was limited and on a small scale. While the Norwegians remained neutral in World War II, France made an agreement with the company to acquire the entire stock of heavy water. But with the invasion of Norway by the Germans, on the morning of April 9, 1940, Norsk Hydro started to meet the Nazi interests in obtaining the precious liquid. To Henriksen the war would be something temporary, so it would be important to keep the jobs and company's business intact.

To give more excitement and make the story more dramatic some fictional characters were drafted, but that did not come to interfere significantly in the actual events that occurred. Among them we can mention Bjørn Henriksen, which was created from three real directors of Norsk Hydro, and his wife, Ellen Henriksen (played by Maibritt Saerens, known for Sykt Lykkelig - Happy Happy - 2010), who also was not part of the original plot, but was responsible for addressing some dilemmas of the couple apart from the moral issues of the war.

Another fictional character is Julie Smith (played by Anna Friel, known for the TV series Pushing Daisies - 2007-2009), who gives life to a British official responsible for the British Special Operations. Here we have to highlight a historical mistake, because in real life the role was played by Scottish Colonel John Skinner Wilson. At that time there were no women occupying the position of command in the army. Despite the good performance of Friel, it would be more appropriate to stick to historical and real facts (put a man) instead of opting for the politically correct of the current times.

The film's director Per-Olav Sørensen depicts in a chronological and historical way the events surrounding the dispute by heavy water. It is noted along the mini-series all the characterization work of an era: uniforms, clothes, cars, equipments and weapons. One bright spot was the maintenance of the three native languages ​​of the countries involved in the plot: Norwegian, German and English. Sørensen also knew how to choose the cast, who gave convincing performances.

The photography is very beautiful and the soundtrack fits well in the plot. However, the director of the mini-series does not do enough to explore more some action scenes and he also could have created more suspense. The rigorous living conditions to which the members of the Norwegian resistance were submitted in missions due to the harsh climate of Norway, as hunger and cold, as well as other difficulties faced when fighting the enemy would have been better dramatized.

This story was also dramatized in a Norwegian docudrama called Kampen om Tungtvannet (Operation Swallow: The Battle for Heavy Water - 1948), in a British production The Heroes of the Telemark (1965), with the participation of Kirk Douglas (citing some of his films: Ace in the Hole - 1951, Paths of Glory - 1957, The Vikings - 1958 and Spartacus - 1960) and Richard Harris (known for A Man Called Horse - 1970) and a Canadian TV mini-series (A Man Called Intrepid - 1979). The Swedish power metal band, Sabaton, also honored this episode through the music called Saboteurs.

The Heavy Water War stands out not only for its compelling historical narrative but also for its remarkable technical execution, especially considering it is a television series rather than a feature film, where resources are typically more concentrated. Despite the broader scope of its multi-episode format, the series manages to deliver a rich, cinematic experience.

The visual storytelling is particularly effective for a television series. The sweeping shots of Norway's icy landscapes feel expansive, yet the intimate, close-up moments that define character development are given just as much care. The varied camera work, such as the occasional handheld shots during moments of peril, intensifies the action, making the stakes feel personal and urgent, a clever use of television's more fluid pacing. This is a rarity for a series where visual cohesiveness can sometimes suffer when stretched across episodes. Yet here, the cinematography remains tight and focused, maintaining the sense of urgency and tension in each scene.

One of the most impressive feats is how The Heavy Water War retains the atmosphere of a high-budget film despite the limitations of a television series. The detailed set designs and period-accurate costuming elevate the experience, creating a world that feels both authentic and immersive, as though viewers are stepping back in time to WWII. Such dedication to realism is more common in films with larger budgets, but the series expertly makes the most of its resources.

Acting is another strong point in this series. Espen Klouman-Høiner's portrayal of Leif Tronstad shines with remarkable subtlety. He captures the character's internal struggles without resorting to melodrama, allowing the emotional weight of his decisions to unfold naturally. The supporting cast also brings depth to their roles, contributing to the overall gravitas of the series. In television, where performances can occasionally feel stretched over long arcs, here, the actors remain grounded and emotionally engaged, a testament to the tight direction and the careful attention to casting.

Even with its reliance on limited resources in comparison to a film, The Heavy Water War excels in technical aspects. The sound design, another often underappreciated aspect of television production, adds greatly to the atmosphere. The wind howls through the mountains, and the rumble of military aircraft enhances the urgency and danger that permeates the show. Although a few CGI moments don't quite match the level of the rest of the production, they don't detract from the overall immersion.

The Heavy Water War demonstrates that a television series can achieve the same cinematic quality as a high-budget film, thanks to its exceptional direction, stunning cinematography, and immersive sound design. Each episode captures the tension and emotional depth of its characters, maintaining a powerful and cohesive narrative from start to finish. The series excels in transforming its historical setting into a living, breathing world, leaving a lasting impression on viewers long after the credits roll.

After watching this, I mentioned to a friend of mine with a degree in physics that Heisenberg really was compromised working for the Germans during the war. He corrected me and suggested I read "Heisenberg's War" by Thomas Powers. Thank goodness, I did. It's an excellent book, and sets the record straight about what Heisenberg did and didn't do, and did and didn't think, during the war.

The miniseries show him trying to dazzle the German military with the destructive potential of his nuclear research, and it shows him working diligently on developing a bomb. What Powers shows, though, is that Heisenberg and the scientists who worked closely with him tried in various ways to discourage the Nazis from pursuing a bomb. And they were successful. After a critical meeting with Speer in 1943, in which Heisenberg emphasized all the problems and pointed out that a bomb, even if it could be developed, would take too long to be used in the war, bomb research stopped, and nuclear research was aimed at a reactor or "energy machine." The Heisenberg group were so horrified by the idea of an atomic bomb that they even signaled to scientists outside Germany that Germany was not working on a bomb, hoping to prevent a world of nuclear weapons. (This was misunderstood by many distrustful Allied scientists, who feared Heisenberg was trying to stop their work so that he could proceed without competition on his own.)

So enjoy the series, but please don't do as I did and take it as factual about Heisenberg's participation in a German atomic bomb program. I suppose that part of the story was added to crank up the excitement and drama.

Incidentally, after the destruction of the Norwegian hydro/heavy water plant and the sinking of the ferry carrying the heavy water, Germany's was completely crippled in its supply of heavy water, never to recover.
