NBC's new mid-season drama The Black Donnellys will premiere on Monday, February 26 (10-11 p.m. ET) -- following the hit drama Heroes (9-10 p.m. ET), it was announced by Kevin Reilly, President, NBC Entertainment.

The Black Donnellys had previously been announced to debut on March 5. Studio 60 on the Sunset Strip (currently Mondays, 10-11 p.m. ET), will return to the schedule later this season on a date to be determined.

Academy Award winners Paul Haggis and Bobby Moresco (both for Crash) are the creators and executive producers of The Black Donnellys, a gritty new drama series filmed in New York City and loosely based on Moresco's background. Haggis is also an Academy Award nominee for the original screenplay, Letters From Iwo Jima.

The series follows the exploits of four young, working-class Irish-American brothers and their involvement in organized crime in New York City. The Donnelly brothers will do anything to protect each other against all odds.

The ensemble cast includes Kirk Acevedo, Thomas Guiry, Billy Lush, Keith Nobbs, Michael Stahl-David, Jonathan Tucker and Olivia Wilde. The pilot was directed by Haggis, who also wrote the Academy Award-winning Million Dollar Baby.
