In 2009, the horror movie Orphan became a hit thanks to its eerie premise and huge plot twist. The 2023 documentary series The Curious Case of Natalia Grace, which is available from Investigation Discovery, tells a very similar story. Kristine and Michael Barnett share that they adopted a girl from the Ukraine and then learned that she was actually an adult. The series is getting a lot of buzz. And while many are tuning in because the story sounds so much like Isabelle Fuhram's Orphan character Esther Coleman/Leena Klammer, the six episodes are gripping enough to stand on their own.
