British actress Dominique Tipper has joined the cast of Syfy’s upcoming 10-episode space-opera series "The Expanse," which is based on the book series of the same name written by Daniel Abraham and Ty Franck, a thriller set two hundred years in the future, that follows the case of a missing young woman who brings a hardened detective and a rogue ship’s captain together in a race across the solar system to expose the greatest conspiracy in human history. What that conspiracy is, you’ll have to wait to find out, when "The Expanse" debuts in 205.

Abraham and Franck will be show producers. Thomas Jane ("Hung," "The Punisher") will played the lead character of Detective Miller, a native of the asteroid belt between Mars and Jupiter. Detective Miller works for a corporate security force that operates as the law in the asteroid belt. Ragged and in search of something he can’t identify, Miller finds a new sense of purpose when he’s put in charge of the investigation of a missing heiress.

Tipper joins a cast that includes Steven Strait, Thomas Jane, Cas Anvar, Wes Chatham, Florence Faivre and Shohreh Aghdashloo. 

No word on what character she’ll be playing, but we do know that her role will be a series regular.

"The Expanse" is produced by Alcon Television Group, a division of Alcon Entertainment.

Academy Award-nominated screenwriting duo Mark Fergus and Hawk Ostby (Alfonso Cuaron’s "Children of Men," "Iron Man") wrote the pilot; they will continue to serve as writers, as well as executive producers.

Relative screen newcomer Dominique Tipper’s resume includes roles in British feature films "Adulthood," and "Fast Girls," both Noel Clarke productions.

This series will introduce her to Stateside TV audiences.
