The CW Network has announced its fall premiere dates. The network will launch several shows the week before the official September 19 start date of the fall season. Here’s the CW Network’s premiere schedule for science fiction and fantasy fans:

THURSDAY, SEPTEMBER 15
8:00-9:00 PM THE VAMPIRE DIARIES (Season Premiere)

‘The Vampire Diaries’ is the story of two vampire brothers obsessed with the same beautiful girl, and battling to control the fate of an entire town. Stefan (Paul Wesley, ‘Fallen’) and Damon Salvatore (Ian Somerhalder, ‘Lost’), returned to their hometown of Mystic Falls, Virginia, for very different reasons – Stefan was determined to get to know Elena Gilbert (Nina Dobrev, ‘The Killing Game’), who bears a striking resemblance to Katherine Pierce, the beautiful but ruthless vampire the brothers knew and loved in 1864, while Damon was intent on releasing Katherine from the tomb where he believed she was trapped by a witch’s spell all those years ago.

Season three opens the door to learn more about Klaus and The Original Family as his motives for wanting Stefan on his side are finally revealed. As Stefan sinks deeper into the dark side, Damon and Elena struggle with the guilt of their growing bond even as they work together to bring Stefan back from the edge. The ghosts from Jeremy’s past have a powerful message they’re trying to deliver to him, not to mention the impact they’re having on his relationship with Bonnie. And as Caroline and Tyler grow closer, a war erupts between their families.

FRIDAY, SEPTEMBER 23

8:00-9:00 PM NIKITA (Season Premiere)

In season one, the charming and deadly Nikita waged a war against Division, the agency that created her. Michael – the man who trained her, a man she trusted – was hunting her. But Nikita had an ace up her sleeve: Alex, a girl she trained to infiltrate this secret unit of the government. At the end of season one, Nikita and Alex’s relationship had been shattered, and Nikita and Michael’s relationship was restored. Now, Nikita and Michael are on the run with a hard drive containing the government’s darkest secrets and conspiracies. Together, they are going to right the wrongs that Division has committed over the years, one mission at a time. But leading the hunt for them this time is Alex…and she knows all of Nikita’s tricks.

The series stars Maggie Q (‘Priest’) as Nikita, Lyndsy Fonseca (‘Kick-Ass’) as Alex, Shane West (‘League of Extraordinary Gentlemen’) as Michael, Aaron Stanford (‘X2’, ‘X-Men: The Last Stand’) as Birkhoff, with Melinda Clarke (‘Slider’,’Chuck’) as Amanda and Xander Berkeley (’24’, ‘Jericho’) as Percy. ‘Nikita’ is produced by Craig Silverstein (‘Bones’ ‘K-Ville’), David Levinson (‘The Commish’), Danny Cannon (‘CSI: Crime Scene Investigation’, ‘Chuck’), McG (‘Supernatural’, ‘Chuck’) and Peter Johnson (‘Supernatural’, ‘Chuck’).

9:00-10:00 PM SUPERNATURAL (Season Premiere)

Returning for its seventh season, this haunting series follows Sam and Dean Winchester, two brothers bound by tragedy and blood to the one thing that runs through both their veins – hunting monsters.

This past season, Dean and Sam faced insurmountable obstacles: Sam returned from Hell without his soul, and Dean risked everything to get it back for him. The power struggle between good and evil raged on, with the new King of Hell, Crowley, ultimately emerging as their adversary. Shockingly, Crowley had made a secret deal with Sam and Dean’s closest friend, the angel Castiel, who is now a desperate freedom fighter on the losing side of a post-Apocalyptic civil war in Heaven; together, the uneasy allies sought to open a door to Purgatory, where a great untapped well of souls lie waiting to be used as the ultimate form of military power.

Sam and Dean reeled from the betrayal by their friend – and raced to stop the angel and demon before they opened that dangerous, otherworldly door. Now, in season seven, the Winchesters will find themselves in an increasingly sinister, changing landscape, up against a new foe unlike anything they’ve ever fought. They’ll find their old tricks, weapons and hiding places all rendered useless. All they’ll have is each other. And the certainty that, like the last of the cowboy outlaws, whatever they face, they’re not going down without a fight.

The series stars Jared Padalecki as Sam Winchester and Jensen Ackles as Dean Winchester. ‘Supernatural’ is produced by McG (‘Charlie’s Angels’, ‘The O.C.’), Eric Kripke (‘Boogeyman’), Robert Singer (‘Midnight Caller’), Sera Gamble, Ben Edlund (‘Lost’), and Phil Sgriccia.
