Joining the 90-minute pilot are Roxanne McKee ("Game of Thrones," "Wrong Turn 5"), Luke Allen-Gale ("The Borgias"), and most notably, Anthony Stewart Head ("Repo: The Genetic Opera," "Buffy the Vampire Slayer"), with Shivani Ghai ("Bride & Prejudice") slated for a guest appearance.
A recent press release from Syfy gave some character details and thus, insight into the roles of these new cast members:
Anthony Stewart Head plays “David Weel,” the power-hungry president of the Senate of Vega (formerly Las Vegas) who is frequently at odds with General Rysen (Alan Dale), the city’s military leader. David is willing to do whatever he believes is right to protect the city and his position leading it.
Roxanne McKee plays “Claire Rysen,” the closest thing that Vega has to a princess. As the daughter of General Rysen – the man who led humans to victory against the angels during the Extermination War – she is a member of the highest class in Vega’s stratified society. Claire is also strong-willed and much tougher than she seems.
Luke Allen-Gale (pictured below right; "The Borgias," "Ripper Street") plays “William Weel,” the scion of Vega’s other powerful ruling family. Unlike his cunning politician father David, William is a man of the people and Head of the Church of the Savior.
Shivani Ghai plays “Arika,” a lead diplomat sent from Helena, a mysterious and militant matriarchal society in what was once Salt Lake City, which maintains a tenuous peace with Vega.
"Dominion" is set 25 years after the events of the movie and picks up in the midst of an epic, world changing war between an army of angels and man. The show will follow a rebellious young soldier, who discovers that he is to become the savior for all mankind.
Scott Stewart, who directed and co-wrote "Legion," is back in the director's chair. He will also be serving as an executive producer, along with Michel Litvak and David Lancaster of Bold Films, who produced the 2010 film. Vaun Wilmott, responsible for writing the pilot, will also serve as a co-executive producer.
The pilot is set to begin filming later this month in Cape Town, South Africa.
