French director Jean-Jacques Annaud sourced actual footage of Notre-Dame blaze for his film

The makers of 'Notre-Dame On Fire' left no stone unturned to lend

authenticity to the film which captures the blaze that took place at

the historic Notre-Dame cathedral and tells the story of many

courageous souls who risked everything to douse the deadly flames.

A stickler for perfection, the director of the film Jean-Jacques

Annaud birthed a new idea to make his film, as the team decided to

source clips of the actual fire that people had recorded.

An exclusive website was set up for the same purpose, and netizens

began submitting a barrage of videos that documented the event.
