Sure, the first '24: Live Another Day' teaser from the Super Bowl was pretty great, as were the photos of all our new cast members, but '24' wouldn't be '24' without Jack Bauer getting back into action for a full trailer! See Jack, Chloe, and a slew of new faces, as the first '24: Live Another Day' trailer finds the former CTU agent in London looking to prevent another World War!

The clock has indeed started ticking, touts the new trailer for the '24' revival that sees Kiefer Sutherland back in action as the iconic Jack Bauer. This time around Jack must first redeem himself in the eyes of those who hunted him through the show's eighth and (formerly) final season, before attempting to foil an assassination attempt on the US President in London, none other than James Heller. "If an American president is assassinated on foreign soil, you're looking at a world war," Jack warns a punked-out Chloe (Mary Lynn Rajskub).

’24: Live Another Day’ will premiere the first two installments of 12 all-new episodes on May 5 with a cast that includes Audrey Raines (Kim Raver) and the now-Presidential James Heller (William Devane),  ‘Dexter‘ star Yvonne Strahovski as a CIA analyst, ‘Game of Thrones‘ star Michelle Fairley (who replaced Judy Davis), ‘Hostages‘ star Tate Donovan, Stephen Fry, Benjamin Bratt as the head of CIA operations in London, and Michael Wincott as an infamous hacker. ‘Live Another Day’ will also have the returning ’24′ team of writers/producers Howard Gordon (‘Homeland‘), Evan Katz, Manny Coto, David Fury, Robert Cochran, Brian Grazer, Jon Cassar and Kiefer Sutherland.

The clock is officially ticking! Get your first look at Jack Bauer back in action with the '24: Live Another Day' trailer above, and tell us what you want to see from the revival series in the comments!
