Cropsey

Year: 2009

Director: Joshua Zeman and Barbara Brancaccio

Rotten Tomatoes: 93%

Plot: Two filmmakers investigate the disappearances of five children from Staten Island and discover that the real-life case has eerie connections to the local urban legend of Cropsey, a supposedly escaped mental patient who supposedly lived beneath the abandoned Willowbrook State School.

Marcela Notes: I honestly don't remember it at all but apparently enjoyed it in the past. Gotta rewatch. 

Fun Fact: The filmmakers began the project because they wanted to investigate whether the childhood legend they had both heard might have been connected to actual missing children.
