Fox is announcing premiere dates of new and returning series as well as revisions to its 2009-2010 midseason schedule. Fox also has ordered a full season of the sophomore drama Lie to Me.

January starts off on a high note when the ninth season of American Idol, television's No. 1 series, begins with a two-night premiere Tuesday, Jan. 12 (8:00-10:00 PM ET/PT) and Wednesday, Jan. 13 (8:00-9:00 PM ET/PT). Immediately following American Idol on Jan. 13 (9:00-10:00 PM ET/PT), Fox unveils the not-to-be-missed series debut of Our Little Genius, a new unscripted series that features America's most gifted kids as they are tested with some of the most challenging and difficult questions that only a remarkable little genius could answer.

A special extended primetime event on Sunday, Jan. 17 kicks off with the NFC Divisional Playoff (4:00 PM-CC ET live/1:00 PM-CC PT live), which leads into the explosive series preview of Human Target (8:00-9:00 PM ET/PT), the new full-throttle, action-packed drama about a unique private contractor (Mark Valley) who will stop at nothing - even if it means becoming a human target - to save his clients. The special primetime event concludes with the first installment of the pulse-pounding two-night, four-hour premiere of 24 (9:00-11:00 PM ET/PT). The season premiere of 24 clocks in for two more hours of action Monday, Jan. 18 (8:00-10:00 PM ET/PT), and the season premiere of Human Target airs Wednesday, Jan. 20 (9:00-10:00 PM ET/PT) following American Idol (8:00-9:00 PM ET/PT).

On Sunday, Jan. 10, FOX presents a special The Simpsons event beginning with the animated series' milestone 450th episode, "Once Upon a Time in Springfield" (8:00-8:30 PM ET/PT), in which Bart (Nancy Cartwright) and Milhouse (Pamela Hayden) try to help Krusty (Dan Castellaneta) regain his popularity after network executives force him to restructure the format of his television show by hiring a female sidekick, Princess Penelope (guest voice Anne Hathaway). Then, Academy Award-nominated filmmaker Morgan Spurlock (Super Size Me, 30 Days) will present The Simpsons 20th Anniversary Special: In 3-D! On Ice! (8:30-9:30 PM ET/PT). The documentary special examines the global phenomenon that is The Simpsons and serves as the momentous conclusion to the "Best. 20 Years. Ever.," a year-long global celebration of The Simpsons that launched in January 2009.
