Created and executive produced by Brit Marling and Zal Batmanglij, the series is their third collaboration. The series consists of two seasons of eight episodes each, mostly directed by Batmanglij, and is produced by Plan B Entertainment and Anonymous Content. In the series, Marling stars as a young woman named Prairie Johnson who resurfaces after having been missing for seven years. Prairie now calls herself "The OA" and can see, despite having been blind before her disappearance.
The OA received generally favorable critical reception. The series' directing, visuals and acting were often singled out.
