Fox has given a put pilot commitment to Blue Blood, a cop drama created by screenwriter Neil Tolkin that Brett Ratner is attached to executive produce and possibly direct, according to Variety.

Based on the bestselling 2004 autobiography by Gotham cop Ed Conlon, Blue Blood is an ensemble hour about a rookie NYPD police officer. The twist: The newbie officer is a Harvard grad who decides to return to the family beat -- law enforcement.

The project is being produced by 20th Century Fox TV via Gina Matthews (13 Going on 30) and Grant Scharbo's Roundtable Entertainment and Ratner's Rat TV shingle.

Tolkin -- currently penning the Nicholas Cage / 50 Cent starrer The Dance for Universal -- will create, write and exec produce the pilot, with Matthews and Scharbo joining Ratner as executive producers.

Tolkin said Blue Blood will not be a standard procedural cop show, instead focusing on the lives of its main characters (a la Grey's Anatomy or Rescue Me).
