Filming for the revived drama has started near Whitechapel in east London, and Sutherland was seen alongside co-star Mary Lynn Rajskub as cast and crew filmed an action sequence in the capital today (Wednesday, January 22).
Sutherland's Jack was also shown pointing a pistol during one scene, appearing to help Chloe (Rajskub) get to safety.
Sutherland recently told Vulture that Live Another Day aims to "get back to that very personal first season" of 24.
"Remember that episode in the first season when Jack was held up in that little construction shack because he can't get outside? The whole episode, he's in there. It was awesome," he explained.
"Later on, Howard [Gordon] and I used to sit and drink and go, 'I remember when it was small, man. When we were doing the drama, the stuff that made people feel'."
Live Another Day is the first season of 24 since the show's original run ended in 2010. The new season, set in London, will see Sutherland's former government agent Bauer hunted by a CIA agent (Yvonne Strahovski).
Benjamin Bratt and Tate Donovan have also been cast in the new season, which will debut on Fox in the US with a 2-hour premiere on May 5. Sky 1 has broadcast rights for the UK.
