The birth date listed on the Raymond Reddington wanted posters is the actual birth date of actor James Spader (February 7, 1960).

Red's signature fedora came about as a result of a suggestion from series star James Spader.

Baz Baz, who plays Red's (James Spader) chief of security Baz, is a veteran US marine and a former member of CIA's Special Operations Group. He is the founder of the Association for the Recovery of Children (ARC), which rescues abducted children. In 1991-2012, they had conducted 56 successful rescues.

Creator Jon Bokenkamp loosely based Raymond Reddington character on the real-life Boston mafia boss, James 'Whitey' Bulger. As explained at the 2013 Comic-Con panel, many news stories concerning Bulger's arrest and trial were prevalent at the time. Bokenkamp tossed around a few "what if?" scenarios and came up with the basic concept of the show, anchored by the nefarious "concierge of crime" we now know as Red. Although Spader came in very late to the concept (within approximately two weeks of the principal shooting of the pilot), he can be credited with largely contributing to the final "look" of Reddington: closely cropped hair, hat collection, Rx shades (for practicality - Spader really does need them to see), iconically tailored vest-tie-trousers-shirt ensemble, and the infamously expensive ($5,000?) all-weather navy blue coat. As for the acerbic humor & raconteur tendencies of Red? Spader claims these were already present in the pilot script, however one can't help but think that the writers expanded these qualities once they got to know Spader a bit better.

Agent Ressler (Diego Klattenhoff) is loosely based on Robert K. Ressler, a former FBI agent and author, who played a significant role in the psychological profiling of violent offenders in the 1970s and is often credited with coining the English term "serial killer". He was also fundamental in the setting up of the ViCAP system . (Violent Criminal Apprehension Program )

Kiefer Sutherland was considered for the part of Red.

In 2013 The Blacklist was NBC's highest-testing drama in 10 years.

Writer John Eisendrath said the casting process was difficult. In February 2013, NBC offered Kiefer Sutherland the lead role of Raymond Reddington.After considering other actors for the role, Eisendrath and Jon Bokenkamp called James Spader to see if he would be interested in it. Feeling confident in Spader's understanding of the character, they cast him three days before filming began.

Megan Boone took a week to prepare for her audition as Elizabeth Keen. Feeling like her initial audition was one of the better auditions of her career, Boone later was called back for multiple auditions. In March 2013, Deadline.com reported that she accepted the role.
