According to TV Line, which first broke the news Friday (Oct. 11), "Nashville" star Michiel Huisman will play Cal Morrison, "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."
Huisman, who plays Rayna's (Connie Britton) producer and lover Liam on the ABC musical drama, has also starred in HBO's "Treme" and will assume the role of Daario Naharis in Season 4 of "Game of Thrones."
"Nikita" villain Peter Outerbridge will also recur as Henrik “Hank” Johanssen, who is described as "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."
Another "Nikita" alum, Ari Millen, will have a multi-episode arc as Mark, "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."
Outerbridge played the deceased baddie Ari on The CW series, which debuts its final season in November, while Millen played a one-off character named Ronnie in the episode "2.0."
"Orphan Black" is slated to return for Season 2 in April 2014 on BBC America. The second season, which is currently in production, hits the ground running with Sarah (Tatiana Maslany) in a desperate race to find her missing daughter Kira (Skyler Wexler). Her scorched earth tactics spark a war with pro-clone, Rachel (Maslany), dividing and imperiling all the clones.
