NBC unveiled today a wide spectrum of its post-January mid-season schedule that features the series premieres of the new drama Kings (March 19) with a two-hour event, plus the season debuts of Medium (February 2) and a two-hour Celebrity Apprentice (March 1) -- as well as original episode returns for Chuck (returning with a special "3-D" episode February 2), Heroes (which begins "Fugitives," a new volume on February 2) and Life (February 4) -- and the movie event XIII (February 8 & 15). All the series and movie events will be given a huge promotional boost during Super Bowl XLIII on February 1.

Immediately following Super Bowl XLIII on February 1, NBC will broadcast an original, hour-long episode of The Office (10:30-11:30 p.m. ET; simultaneously to all time zones). Noteworthy announcements regarding this special episode are forthcoming.

In addition, NBC has scheduled the two-hour series finale of ER for Thursday, March 12 (9-11 p.m. ET).

Premieres for additional mid-season shows -- The Untitled Amy Poehler Project and The Philanthropist - will be announced at a future date.

The announcements were made by Ben Silverman, Co-Chairman, NBC Entertainment and Universal Media Studios.

"February and March are going to be exciting months on NBC and the Super Bowl is just the beginning," said Silverman. "The biggest event on television will provide the perfect promotional platform as we launch some of the most eagerly anticipated new and returning shows on any schedule."

Beginning February 2, Monday nights will feature original episodes of Chuck (8-9 p.m. ET), the latest volume of Heroes (9-10 p.m. ET) and the return of Medium (10-11 p.m. ET).

Kings

From executive producer Michael Green (NBC's Heroes) comes Kings, a riveting new drama about a modern-day monarchy. Kings is a contemporary retelling of the timeless tale of David and Goliath. This series is an epic story of greed and power, war and romance, forbidden loves and secret alliances -- and a young hero who rises to power in a modern-day kingdom. King Silas Benjamin (Ian McShane, Deadwood) is the well-entrenched king of Gilboa, with its capital in Shiloh, a clean new city that is unspoiled by time or litter. Silas must deal with the tensions rising between Gilboa and neighboring nation Gath. When several prisoners of war are taken, a young soldier, David Shepard (Chris Egan, Eragon), defies orders and crosses enemy lines to save them. Unknown to David, the soldier he saves is Jack Benjamin (Sebastian Stan, The Covenant), the son of the king. From that day forth, David's life will never be the same.

Also starring are Susanna Thompson (Once and Again), Allison Miller (Lucy's Piano), Wes Studi (Comanche Moon, Bury My Heart at Wounded Knee), Eamonn Walker (Oz) and Dylan Baker (Spider-Man 2). The series is from Universal Media Studios. Kings is executive-produced by Green, Erwin Stoff ("I Am Legend) and Francis Lawrence ("I Am Legend"), who also directed the pilot.

XIII

XIII is a high-stakes cat-and-mouse thriller starring Val Kilmer (The Doors), Stephen Dorff (World Trade Center), Stephen McHattie (Watchmen) and Jessalyn Gilsig (NBC's Heroes). The adrenaline-charged miniseries begins dramatically as the first female U.S. president is shot dead by a sniper during her Veterans Day speech. Three months later, a wounded man is found tattered in a forest with no memory of his identity. The only clue is a tattoo on his neck -- XIII. Could his lightning-fast reflexes and killer instincts betray him as the presidential assassin that the U.S. is desperately searching for? Submerged in a far-reaching conspiracy, which threatens to overthrow the entire government, XIII's identity becomes the key to unraveling a complex and dangerous secret that will shock and excite. From the first bullet, this gripping action-thriller will leave audiences gasping for more. Ted Atherton (Max Payne), John Bourgeois (Burn Up), Greg Bryk (ReGenesis), Lucinda Davis (WarGames: The Dead Code), and Caterina Murino (Casino Royale) also star. XIII is an official Canada/France co-production, developed and produced by Prodigy Pictures and Cipango in association with Power. Prodigy Pictures' Jay Firestone, Cipango's Edouard Vesinne and Thomas Anargyros and Power's Justin Bodle will serve as executive producers. Directed by Duane Clark (CSI, Meadowlands), XIII is written by David Wolkove (La Femme Nikita, Relic Hunter) and Philippe Lyon (The Trail, Alive).

Celebrity Apprentice and host Donald Trump will return with two-hour episodes and a dynamic cast of brilliant celebrity business minds. Last season saw Piers Morgan defeat Trace Adkins to become the first Celebrity Apprentice. This season, 16 new celebrities will be vying for the coveted title, using all their business savvy as they fight for causes close to their hearts. Celebrities will be subjected to long hours, grueling mental challenges, personality clashes, and intense scrutiny -- all without the help of their regular support system of agents, managers, and personal assistants. Ultimately, they will face the judgment of Donald Trump and his advisors in the boardroom, which will include his children (and colleagues), Ivanka Trump and Donald Trump Jr.
