Laid off from his job, "Robinson" (Jude Law) gets wind of a rumoured sunken horde of Nazi gold at the bottom of the Black Sea. He manages to cobble together some funds, recruit the ultimate in disparate crew - half British and half Russian, and somewhat implausibly obtain a WWII submarine that is only really held together by rust. Off they go in search of their loot and, as you might expect, tempers and superstitions run riot as the claustrophobic environment and cultural clashes cause difficulties for the increasingly isolated skipper. At times the imagery is quite effective at conveying some of the peril as their boat lurches from one disaster to another, but for the most part this is a really poorly constructed drama let down at pretty much every turn by Law's over-acting, his intermittent Scots accent, some very ropey dialogue and a cast of people who would usually perform better - Ben Mendelsohn and David Threfall, especially - but who really don't deliver anything substantial in this really cheap and cheerful looking effort. Some of the submarine interiors are authentic enough - a real one was used - but that can't really compensate for the lacklustre and repetitive narrative that can have but one conclusion. Not one of Kevin MacDonald's finer works - despite the decent cast.
