How many episodes will it take for Jack Bauer to shoot a tranquilizer dart into Benjamin Bratt's upper-thigh? We'll find out when 24: Live Another Day debuts in May, with the Law & Order veteran along for the ride.

Fox has announced that Bratt is the latest actor to board the 24 revival, playing Steve Harris, head of the CIA operation responsible for tracking Jack Bauer through London. He's the second high-profile cast addition this week, following on the heels of Yvonne Strahovski's hire as CIA operative Kate Morgan.

Bratt's Harris and Strahovski's Morgan are joined by CIA computer tech Jordan Reed (played by Jobs actor Giles Matthey) and arrogant field operative Erik Ritter (played by Gbenga Akinnagbe of The Wire).

The new cast members join several returning 24 players, including Kiefer Sutherland as the legendary Jack Bauer, Mary Lynn Rajskub as computer hacker Chloe O'Brien, Kim Raver as Audrey Raines and William Devane as James Heller.

24: Live Another Day debuts on May 5.
