This 1965 WWII “men on a mission” film is based on the real-life exploits of a small team of Norwegian saboteurs, who were tasked with preventing the Nazis from manufacturing ‘heavy water’, essential for production of an atomic bomb.

Kirk Douglas and Richard Harris offer strong chins and a miso-mash of accents as the leads.

Truth be told, its rather slow and takes a long, long time to get going. But the snowy Norwegian landscapes are impressive, and the finale (when the team of commandoes manages to sink the heavy water barrels aboard a ferry crossing a fjord) does pack a punch.

I have amassed various memorabilia items, including the Belgian poster above, and booklets in both English and French. The French one has sold, the other items are for sale here.
