BBC America has renewed its clone drama "Orphan Black" for a fifth and final season. The ten episode final bow for the Tatiana Maslany-led drama will air in the second quarter of 2017, and follows on from the fourth season which wraps its run tonight. Executive producers David Fortier and Ivan Schneeberg said in a statment: "We are so proud of the cast and crew, who will be on this final ride with us as we draw the 'Orphan Black' story to a close, and extremely thankful to our partners at BBC America and Space for their continued support, as well as the legions of fans who have made these five seasons possible."
