If you were looking for a director for the movie version of Edge of Darkness, you'd have thought you couldn't do better than Martin Campbell, who made the original 1985 series for BBC television. He's now a bona fide Hollywood ace, with a string of major TV credits and hit movies like Casino Royale and the Zorro flicks to his name. But not even a Tinseltown budget can bribe lightning to strike twice, and whatever fortuitous combination of timing and subject matter turned the BBC series into an instant historic event, it's difficult to imagine that happening to its big-screen incarnation.
