Greed, fear and claustrophobia are the ingredients for an initially promising deep-water thriller set in a submarine, scripted by Dennis Kelly (author of the excellent Sharon Horgan TV comedy Pulling) and directed by Kevin Macdonald. The film is more Ocean’s Eleven than Das Boot: it’s good to see it avoiding cliches like shouting “dive” three times (once turns out to suffice) and doing the up-periscope manoeuvres. Jude Law plays Robinson, a tough Scottish submarine captain and ex-Navy man heartlessly laid off by a marine salvage company, who hears about the existence of a Russian submarine that went to the bottom of the Black sea during the second world war, loaded with Nazi gold from Soviet foreign-currency reserves. Some shadowy types are funding a criminal scheme to find the craft and spirit away the loot – but they need an experienced captain with the balls to go down there. It’s a nice idea, but the actual shenanigans aboard the sub turn out to be oddly strained and dependent on sudden, extravagant and bizarre acts of psychotic violence. These progressively undermine confidence in the drama, which is heading for a watery grave.
