The drama - known in Norway as Kampen om tungtvannet - tells the true story of how Norwegian saboteurs destroyed Nazi Germany's hopes of developing an atom bomb during the Second World War.
The series covers key events in the 1930s and 1940s, which saw the Nazis come close to developing a nuclear weapon to use on their enemies.
Espen Kloumann Høiner, Dennis Storhøi and Christoph Bach lead the cast, with Anna Friel starring in a supporting role.
The opening episodes of Heavy Water War were seen by more than 1.2 million Norwegians when they premiered on Nrk in January.
Heavy Water War will air on More4 later this year.
