In 1944 Norway which is under Nazi occupation, a group of resistance fighters attempt to sabotage a factory which is producing heavy water which will be used in the development for the first atomic bomb. Based on a true story, Anthony Mann directs this WWII diverting action adventure but with none of the distinction that earmarks his best films. A few years later, this kind of thing would be done better with WHERE EAGLES DARE. It's kind of hard to accept Kirk Douglas and Richard Harris as Norwegians, not surprisingly the Swedish Ulla Jacobsson (Bergman's SMILES OF A SUMMER NIGHT) is more convincing. The snowbound landscapes are handsomely photographed in wide screen Panavision courtesy of Robert Krasker (EL CID) and Malcolm Arnold keeps things stirred up with his regal score and the film's last ten minutes are filled with genuine nail biting tension but mostly it feels generic, lacking a strong sense of focus. With Michael Redgrave, Anton Diffring, Barry Jones, Geoffrey Keen, Mervyn Johns and Faith Brook.
The Carlton DVD from Great Britain is in its proper wide screen ratio (2.35) but it's a rather soft transfer, lacking clarity and sharpness.
