The clocks have started ticking as the countdown begins to the new series of 24: Live Another Day, and to tease fans all the more Fox has released a trailer offering a tantalising taste of Jack Bauer's next adventure.
In an explosive 30-second clip, Kiefer Sutherland's action hero is caught up in a transatlantic terror plot involving an assassination attempt on the fictional US President James Heller during a visit to Britain.
This time though, Bauer is in exile in London, and trying to avoid capture by the CIA, as he races against time to save the world in the space of 24 hours.
In new footage, audiences are given mere snippets featuring Bauer wearing his tradmark obligatory scowl as he shoves a gun in someone's face, kicks down a door and runs away from a fireball.
The 12-part series has been filmed in London and features shots of Tube trains and the Houses of Parliament.
Stephen Fry will be making an appearance as the Prime Minister Trevor Davies.
The revival also stars Benjamin Bratt, Yvonne Strahovski and Tate Donovan.
The first two episodes of 24: Live Another Day will be broadcast on May 5th on Fox.
