Action miniseries explodes onto Pay TV

False Witness premieres on UKTV this Sunday.

There's an energetic new locally-produced thriller airing this weekend on Aussie television with a host of familiar faces -- but not on free–to-air television.

False Witness is a lavish two-part spy tale set in Sydney, London and Tajikistan, to screen on the UK TV channel.

Starring Dougray Scott (Desperate Housewives), Richard Roxburgh (East of Everything), Jeremy Lindsay-Taylor (Sea Patrol) and Rachael Blake (Suburban Shootout), it is inspired by the true-life theft of five Soviet nuclear "suitcase bombs".

Others in the cast include Claire Forlani (CSI: New York), Stephen Curry (The King), Don Hany (East West 101), Chris Haywood (Breaker Morant, Strikebound) and Tony Martin (Wildside, The Interview).

Some of the cast don foreign accents as either good guys or bad guys before a backdrop of bickering intelligence agencies, fallible police forces and international tensions.

The series is put together by the team behind Underbelly. Written by screenwriter Peter Gawler it explores "the murky world of international intelligence with an explosive and unstoppable chain reaction of events".

Des Monaghan, executive producer said, "Screentime is committed to creating provocative and engaging work and proud to be making this gripping, acutely relevant project."

As a pay television drama channel, UK TV is required to invest some of its production in local television, recently also producing Mike Bullen's Make or Break pilot.

False Witness is far more ambitious, and will screen internationally, including on cable television in the US where it is to be titled The Diplomat.

False Witness screens 8:30pm Sunday January 11 and Monday January 12 on UKTV and BBC HD.
