We told you back in May about Syfy‘s straight-to-series order for Killjoys, which is coming from Temple Street Productions, the company who produces Orphan Black. We knew then that it would be space-based, and we had a brief synopsis. What we didn’t have was the cast, until today.

Syfy has now announced that Aaron Ashmore, Steve Jinks from the recently concluded Warehouse 13, will be starring in the series, along with the equally attractive Hannah John-Kamen and Luke Macfarlane. Here are the deets:

SYFY, SPACE AND TEMPLE STREET PRODUCTIONS ANNOUNCE HANNAH JOHN-KAMEN, AARON ASHMORE AND LUKE MACFARLANE WILL STAR IN NEW SCRIPTED SERIES KILLJOYS

FROM THE PRODUCERS OF ORPHAN BLACK AND THE CREATOR OF LOST GIRL

10-EPISODE SPACE ADVENTURE SERIES BEGINS PRODUCTION IN TORONTO AUGUST 5

NEW YORK – July 22, 2014 – Syfy, Space and Temple Street Productions announced today that Hannah John-Kamen, who starred in the West End musical Viva Forever, Aaron Ashmore, who played Steve Jinks on the long-running Warehouse 13, and Luke Macfarlane, who portrayed Scotty Wandell in the popular Brothers and Sisters, have been cast as the leads in the upcoming original space adventure drama series Killjoys.

From Temple Street Productions, the producers of Orphan Black, and Michelle Lovretta, the creator of Lost Girl who will serve as writer and showrunner, Killjoys follows a fun-loving, hard living trio of interplanetary bounty hunters sworn to remain impartial as they chase deadly warrants throughout the Quad, a distant system on the brink of a bloody, multi-planetary class war. Chris Grismer (Vampire Diaries) will direct the pilot and additional episodes.

Commissioned by Space and produced by Temple Street Productions for Space and Syfy, the 10-episode, one-hour series will begin production in Toronto on August 5. Killjoys will premiere on Syfy and Space in 2015.

In Killjoys, Hannah John-Kamen stars as the gorgeous, complicated, and deadly Dutch. A top-level Killjoy, she’s a much loved and charming presence in her community, with a unique gift for earning people’s trust and respect regardless of their class. Under her banter and protective flirtations, there is pain, maturity, and a deep solemnity resulting from a dark secret past.

Aaron Ashmore takes on the role of John Jaqobis, a peacemaker who hates conflict. Cheerful and kind-hearted, John prefers not to fight, but his sarcastic wit has put him into the fray enough over the years to teach him how to do it well, and dirty.

Luke Macfarlane stars as D’avin, a handsome, rugged, sarcastic, and incredibly loyal former soldier. He dreamed of enlisting in the military since boyhood, and his hard-won expertise in tactics, maneuvers and hand-to-hand combat make him an instant asset to the Killjoy team.

Said Bill McGoldrick, Executive Vice President, Original Content, Syfy: “We’re very fortunate to have these three very talented young actors join the outstanding Killjoys creative team.”

“Hannah, Aaron and Luke are the perfect combination to lead this exciting new drama series,” said Corrie Coe, Senior Vice President, Independent Production, Bell Media. “With only two weeks remaining until the start of production, we look forward to seeing the universe this trio will bring to life with our stellar partners, Temple Street Productions and Syfy.”

“We’re absolutely thrilled to have Hannah, Aaron and Luke sign on to play our stalwart team of bounty hunters,” commented Ivan Schneeberg and David Fortier, Executive Producers and Co-Presidents of Temple Street Productions. “We’re looking forward to getting production underway with this killer ensemble and our partners Space and Syfy.”

Killjoys was created by Michelle Lovretta who also serves as executive producer and showrunner. Executive producers are David Fortier and Ivan Schneeberg of Temple Street Productions. Director and Consulting Producer is Chris Grismer. Producer is Karen Troubetzkoy. Writers are Jeremy Boxen, Emily Andras and Adam Barken. Universal Cable Productions distributes the series worldwide.

Killjoys is produced by Temple Street Productions in association with Bell Media and Syfy. Production Executives for Bell Media are Trish Williams and Rebecca DiPasquale. Corrie Coe is Senior Vice-President, Independent Production, Bell Media. Catherine MacLeod is Senior Vice-President, Specialty Channels and Bell Media Production.
