Stirling introduces me to his ‘office’, a Portakabin that feels like an Arctic refuge, filled with fleeced-up Stirling & Son employees warming themselves with tea. One of Integrity’s crew, Col. Kevin ‘Kev’ Oliver, a mountain leader officer in the Royal Marines, turns up looking every inch the trim, chiselled genuine article. His 33 years in the forces include tours in several global hotspots, and in 2009, Oliver and fellow marine Major Tony Lancashire attempted the Northwest Passage in a 17ft open boat, sailing west to east.

To steer a small wooden boat through the fragmented and kaleidoscopic 6,000-mile labyrinth of ice, islands and straits of the Canadian Arctic presents immense challenges. If ice conditions are heavy there is a risk of getting trapped. The chances are 50/50.

The irony of all this effort is that the Passage is not considered a viable trade route. ‘Even if the ice breaks, the Passage is easily choked,’ says Oliver. ‘In winter it is impassable, even with ice breakers.’ Also found the ending somewhat abrupt, although to me it actually wasn't a predictable one. Although the use of the foghorn is creepy and leaves one feeling unsettled, it could have been used less and not emphasised as much as it was.

While 'Dangerous Crossing' didn't strike me as a great film and could have been better than it was, especially considering that its potential was hardly small in the first place, a lot works in its favour and far outweighs the not so good. And if asked as to whether to recommend 'Dangerous Crossing', my answer would be a solid if not quite enthusiastic yes. There are a lot better films of this type and there are also worse, if this is the sort of film that appeals to you there should be plenty to like even if it doesn't reach masterpiece level.

(‘Will produced the last two.’) Newman (1909-) had a steady Hollywood career being an assistant director on 17 mostly mainstream musicals and dramas whilst in his twenties.Omar Epps, the film's star, spoke a bit more positively about his experience in Ghana. He said that he was able to spend a good deal of time with Ofosu in preparing for the role. Epps also said that he had learned to speak a little bit of Twi.
