Check out this new promo for Fox's 24, which returns Jan. 17 with Kiefer Sutherland as Jack Bauer and Battlestar Galactica's Katee Sackhoff as a new regular cast member.

The promo for the upcoming eighth season features Jay-Z, Rihanna and Kanye's "Run This Town." It expires at midnight this Thursday, so catch it while you can! (There's not much more than a glimpse of Katee, so we'll just have to tune in to see what she does.)

The two-night, four-hour season premiere of 24 kicks off Jan. 17 at 9 p.m. ET/PT. (And here are our reasons why 24 is sci-fi.)
