Pretty solid stuff
8 December 2000 | by action-6See all my reviews

"Kampen om tungtvannet"("The Battle for the heavy-water") is a movie about how Norwegian saboteurs destroyed the factory at Rjukan, which produced heavy-water, which again was vital for making a German atomic-bomb. Some of the guys playing the Norwegian saboteurs are the real men, who risked their lives by blowing up the factory at Rjukan. The acting isn`t the best, but remember that the movie is from 1948, and the fact that this is no American blockbuster. If you can forgive it for having these flaws, you should be able to enjoy it. 7/10
