The hit new thriller from SPACE and BBC America is adding to its roster for the upcoming second season. BBC America announced today that Orphan Black has added three new cast members for the 2014 season, which will be comprised of 10 new episodes.

The fantastic Tatiana Maslany stars in the series as Sarah, a Londoner who learns that she is part of a secret cloning program and worldwide conspiracy. Maslany also plays clones Alison (an uptight suburban housewife), Cosima (a genius genetics student), Helena (a psychopathic killer), and newly-introduced “pro-clone” Rachel (who appears to be on the inside of the organization that created the clones).

Michiel Huisman (World War Z, Nashville) joins the show in the recurring role of Cal Morrison, described by the network as “a rugged, resourceful outdoorsman with surprising emotional depth and a sixth sense about people and situations. Cal will need all his wits and humanity as he crosses paths with the clones. His journey will be fraught with surprise, danger, and revelations he could never see coming.”

Peter Outerbridge (Nikita, Beauty and the Beast) will play Henrik “Hank” Johanssen, “a mercurial modern-day cowboy. Johanssen leads a flock of followers that have broken away from the old world “Prolethean” brotherhood. Under his messianic vision, the age old divide between science and religion has merged, forming a new and formidable threat.”

Finally, Ari Millen (Rookie Blue, Nikita) will play Mark, described as “a cunning predator with a dark edge. Mark is utterly devoted to Johanssen, who took him in and built him into a true believer in the cause. Now, guided by twisted morality and desperate faith, he’s a relentless and dogged pursuer of the clones.”

Also returning in Season Two are Jordan Gavaris (Sarah’s foster brother, Felix), Dylan Bruce (Beth’s former boyfriend, Paul), and Kevin Hanchard (Beth’s former partner, Detective Bell).

The network also release this very teasery summary of what’s to come:

Season two of the series hits the ground running with Sarah (Tatiana Maslany, Picture Day, Parks and Recreation) in a desperate race to find her missing daughter Kira (Skyler Wexler, Carrie). Her scorched earth tactics spark a war with pro-clone, Rachel (Maslany), dividing and imperiling all the clones. As Sarah discovers more about her past, mysterious newcomers appear, but can they be trusted?

Orphan Black is produced by Temple Street Productions for BBC America and SPACE, and distributed internationally by BBC Worldwide. Season Two is now filming in Toronto, through February. Read more about the upcoming season from the executive producers here.
