‘No-one escapes the witching hour.’
3:15 am is a 2017 French found footage anthology horror film consisting of segments directed by David Tillault, Nicolas Delage, Frédéric Gros, Sabrina Kerrar and Evelyne Phan. Producer Fabien Delage (Cold Ground; Fury of the Demon; Dead Crossroads) also directed one segment entitled “The Grove”.
“The hour between 3am and 4am is referred to as “the witching hour” because it’s thought that paranormal forces are at their strongest during that time.
The history behind this comes from the fact that the Catholic church’s prayers and services are marked by the Canonical hours, which are three hours in length. Between 3am and 4am there were no prayers, making it prime time for evil forces…”
