James Wong and Glen Morgan's brief from Fox was to lose the serial killer theme week after week and pursue the origins and workings of The Millennium Group.
The first episode in the series to actually display the name of the episode in its opening credits.
The first Chris Carter heard about James Wong and Glen Morgan taking over Millennium (1996) was when he was told that a deal had been struck. Nevertheless Carter highly approved of their signing as they had done such a good job on The X-Files (1993).
Despite appearing in the opening credits, Megan Gallagher actually appears in fewer episodes in Season 2 than series regular Terry O'Quinn.
