The Plot: Dougray Scott is Tom Jericho, a master crypto-analyst who’s credited with cracking the Enigma code - only to find that it’s changed again. Now he has to race against time to break the new cipher before an allied shipping convoy is blasted from the sea. But there’s a problem: a spy in Bletchely Park’s Station X...

The Background: Hollywood sub-drama U-571 had British stiff upper lips in a froth when it rewrote history, suggesting the Americans, not the Brits captured the Nazi’s code-making Enigma machine during World War Two. Enigma - based on Robert Harris’ bestseller - aims to set the record straight. According to director Michael Apted, this war-time spy yarn is as much a story of unsung heroes as it is a tale of complicated codes. "What was amazing about Bletchley Park is that no one knew anything about it for 30 years," he told Total Film when we popped along to the set. "The element of secrecy surrounding it is spectacular."

The Buzz: With Jeremy Northam joining the cast, a script by Tom Stoppard and a producer credit for old rubber-lipped Mick Jagger, there’s no secret about Enigma’s pedigree: best of British.
