Not much of it is credible, starting with the hiring of a rusty submarine out of Sevastopol, but it has action and adventure to burn, leavened with bits of humour.

Too often, moviegoers must choose between character-driven drama and edge-of-your-seat action. "Black Sea" has both, with a gripping performance by Jude Law as their nexus.

Black Sea is a submarine thriller set in the murky depths of exactly where the title says.

Law’s intensity carries the audience every step of the way.
