24 IS BACK !!! Photos Of Bloodied Jack Bauer And Chloe On The Street Of London In Newest Season

The newest season of 24 looks to be as explosive as ever, as first pictures of the cast filming on Wednesday show the action has relocated to London.

Kiefer Sutherland looked grim-faced as he prepared to reprise his role as former CTU agent turned fugitive Jack Bauer for the scenes. 

Prior to filming, Kiefer admitted to being more than a little anxious about the project, saying: 'I'm terrified. I won't lie to you.

'Until we start shooting, I'm about as anxious and wound up as I've been in a long time.'

After the end of the last series, Kiefer's Jack Bauer remains a fugitive and CIA agent Kate Morgan, played by Chuck star Yvonne Strahovski, is after him.

'In the minds of the CIA, he’s not quite Osama bin Laden but he’s a fugitive of a high order,'  executive producer Evan Katz said.

The series, which originally ran for eight seasons between 2001 and 2010, won an Emmy award for Outstanding Drama Series in 2006, and Sutherland won an Emmy for Outstanding Lead Actor in a Drama Series in the same year.

Kiefer also recently said that the new series doesn't necessarily mean that a 24 movie won't happen.
