This documentary goes through various stories of different feral children. It does a good job covering Itard and Victor in France and Genie in California, but it gives other stories like Oxana from the Ukraine. The video covers language components, culture, and the challenges that feral children have to adapt.
I use this video in my psychology and my sociology course.
There are 6 short answer questions and it comes with an answer key. The video is free on YouTube: https://www.youtube.com/watch?v=DD-pZ7LwL4A
