Frank Black (character)

After retiring from the FBI, Black moves to Seattle, Washington, and begins to consult for the Millennium Group, a private investigative organisation that aid law enforcement in violent criminal cases.

[6] Several months later, Black is able to work with FBI agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) to foil a last-ditch effort by the Group to bring about the end of the world; vindicated, he reunites with Jordan after the case.

[8] Carter saw Black as an archetypal Western hero, describing him as "self-reliant, quiet, capable, dangerous" and comparing him to the title character of the 1953 film Shane.

[12] The initial casting of Henriksen was not well received by executives at Fox Broadcasting Company, who had envisioned the lead role being played by "someone hot and in his mid-thirties, at worst" according to producer Ken Horton.

[13] Producer John Peter Kousakis has noted that Black remained the main constant throughout the series, as each season featured a marked change in tone and plotting.

Club, Zack Handlen noted that "Henriksen invests [Black's] world-weariness with a soothing, almost beautiful patience, and those few moments of delight he's allowed on the show [...] are sincere instead of cloying".

[21] Writing for Slant magazine, Keith Uhlich described Henriksen's portrayal of Black as "the perfect actorly complement to Carter's thematic obsessions", calling the character a "mortal survivalist pushing ever-forward, even in the face of the devil's idle temptations".
