Previous versions

The same story was covered in the 1948 Franco-Norwegian film Kampen om tungtvannet (also known as La bataille de l'eau lourde or Operation Swallow: The Battle for Heavy Water). Quite faithful to real events, it even had many of the original Norwegian commandos starring as themselves.

The 1965 British film The Heroes of Telemark, starring Kirk Douglas and Richard Harris, was another version of the story.

Ray Mears presented a documentary called The Real Heroes of Telemark in 2003. Despite mainly sticking to the factual evidence, some scenes in the documentary were partly dramatised, focusing on the survival skills involved in the operation.
