Wolfpack: Film charts lives of brothers held in New York apartment

They lived their lives trapped inside a New York apartment, home schooled and allowed out very rarely by their father, who had the only key.

To pass the time, the six Angulo brothers turned to cinema, seeing and forming their opinion of the world through the eyes of Hollywood movies.

Now, a film called Wolfpack tells their incredible story, all thanks to a chance encounter with film director Crystal Moselle.
