After having seen a recent and captivating interview with Mukunda Angulo on the Swedish talk show "Skavlan", I found out about the documentary "The Wolfpack" (2015) directed by Crystal Moselle.
It deals with the isolation that Mukunda and his brothers experienced when they weren't allowed by a controlling father to participate in life outside their apartment on the Lower East Side of Manhattan. Homeschooled by their mother, the brothers just went outside a few times a year. The only connetion they had with the the world outside was through the movies.
