24 comes back in an explosive way on January 17, 2010. The just released trailer is below.

Looks like a retired Jack gets dragged back into duty and is joined in his quest again by Chloe O’Brian (who is sporting some serious sexy hair!), Renee Walker, & Elisha Cuthbert (not to mention Freddie Prize Jr & Katie Sackhoff). As a new grandpa myself, I hope nothing happens to his grandbaby!

Check out the trailer for what’s upcoming in Jack’s latest, very bad day (video below)!
