Season Four premieres on Friday, September 28 in a new timeslot: 10 p.m. Eastern/Pacific, 9 p.m. Central. Atlantis‘s mid-season finale (“This Mortal Coil”) will air on December 7, and will feature the return of former series regular Torri Higginson as Dr. Elizabeth Weir.
In the episode, “the Atlantis team must ally itself with a known enemy to join forces against an even greater foe,” the site said. Based on currently known spoilers, it is believed that the Atlantis team allies with the Wraith against the human-form Replicators. Sheppard’s Wraith ally from last year’s “Common Ground” will return in Season Four.
It is believed that the network will air the full season straight through with only a break for Thanksgiving and the December holiday season, though SCI FI has yet to confirm this. If true, new episodes will pick up with “Be All My Sins Remember’d” in early January.
Sky One in the U.K. has not yet announced its premiere date for Atlantis Season Four.
Check out SCI FI Wire for the original story, which also includes details on the Battlestar Galactica telemovie “Razor” and the network’s “minisodes” set to air in the weeks leading up to the November broadcast.
