BBC America has greenlit Intruders, an eight-episode original series based on Michael Marshall Smith’s 2007 novel The Intruders. Glen Morgan (The X-Files, Those Who Kill) is the writer and executive producer on the series that’s about a secret society devoted to chasing immortality by seeking refuge in the bodies of others. BBC Worldwide Prods is producing, with production to begin in early spring 2014. Jane Tranter and Julie Gardner are exec producing, and BBC Worldwide is handling global distribution. The Intruders joins BBC America’s breakout original drama Orphan Black. Meanwhile, the network rankled fans when it cancelled its first original scripted series, Copper, last month.
