Millennium is a crime-thriller television series which was broadcast from 1996 to 1999. Created by Chris Carter, the series aired on Fox for three seasons with a total of sixty-seven episodes. It starred Lance Henriksen, Megan Gallagher, Klea Scott and Brittany Tiplady. Henriksen played Frank Black, an offender profiler for the Millennium Group (a private investigative organisation). Black retires from the Federal Bureau of Investigation to move his wife Catherine (Gallagher) and daughter Jordan (Tiplady) to Seattle, where he begins consulting on criminal cases for the group. After the group's attempt to cause an apocalyptic viral outbreak kills his wife, Black returns to the FBI to work with new partner Emma Hollis (Scott) to discredit the group.
Black was one of the first elements conceived for the series, the remainder of which were fleshed out by Carter around his character. Black has been described by a producer as Millennium's constant, as the series' tone and direction changed around him with each successive season. Except for Frank Black, the series' characters have been criticized as one-dimensional, "generic" and little more than "symbol[s]". Television critic Robert Shearman said that the series featured "half a dozen actors who could be termed regulars [...] but without exception they remain functional ciphers".
The following is a list of characters who have appeared in five or more episodes of the series.
Black (Lance Henriksen) began his career as an offender profiler for the Federal Bureau of Investigation (FBI). However, he retires when he discovers that his family are being threatened by a stalker who mails Polaroid photographs of them to him. Black moves to Seattle to consult for the Millennium Group, a private investigative organisation. Despite his career change, the stalker catches up to him and kidnaps Catherine. Black rescues his wife, killing the stalker. Disturbed by the abduction and Black's rage, Catherine moves out of their home with Jordan.
