Netflix subscribers browsing the streaming library are now able to press play on Orphan Black, the Tatiana Maslany-starring show created by screenwriter Graeme Manson and director John Fawcett that ran for a total of 50 episodes from 2013 through 2017. All five seasons of the hit series started streaming on Netflix on September 1, 2025. Orphan Black is headlined by Maslany as Sarah, a street-wise woman with a troubled past who is pulled into a world of secrets after witnessing the suicide of a girl who looks just like her. She soon learns that she is one of several genetically identical human clones. Dylan Bruce, Jordan Gavaris, Kevin Hanchard, Michael Mando, Maria Doyle Kennedy, Evelyne Brochu, and Ari Millen also star.
Why You Should Watch Orphan Black
Orphan Black is a masterclass in the sci-fi thriller genre that offers a compelling, high-stakes science fiction plot that will have viewers on the edge of their seats from beginning to end. The mind-bending narrative of the show is incredibly addictive and fast-paced, features frequent twists, and isn’t afraid to raise moral and ethical questions. We’d also be remiss not to mention Maslany, whose Emmy-winning performance in multiple roles is a standout of the show and her career. Throughout the series, Maslany portrays several different clones, bringing a unique personality and nuances to each, including some in the same scene.
Orphan Black’s incredibly engrossing narrative and characters earned it a strong fan base during its five-season run, and the show received plenty of praise. The series holds an overall 93% critics’ score and 92% audience rating on Rotten Tomatoes, and it received numerous accolades during its run, including several for Maslany’s performance, as well as a Peabody Award in 2013 and several Canadian Screen Awards. A spin-off, Orphan Black: Echoes, ran for a single season in 2024. It is available to stream on AMC+.
