Bird Box has garnered more controversy, this time for the decision to feature actual footage of a real-life disaster.

Bird Box, starring Sandra Bullock as a woman trying to protect two children in a world where sight has become a liability, has become a hit for streaming service Netflix. However, the horror film has also proven to be controversial since its release, partly because of a dangerous viral sensation known as the Bird Box Challenge, which saw people blindfolding themselves and entering potentially hazardous situations. Netflix has come out against the challenge, but a new controversy over the film regards the movie itself.

As reported by EntertainmentWeeklyBird Box used real-life footage of Canada’s Lac-Mégantic rail tragedy. The clip is shown during a montage of modern society crumbling towards the beginning of the film. In 2013, a train carrying crude oil derailed in the town of Lac-Mégantic, causing explosions that leveled much of the downtown area and is believed to have killed 47 people.

Another Netflix production, the sci-fi series Travelers, also used the footage. The production company behind the show, which is partly based in Canada, has said they will remove the footage and refrain from using it in any future productions.

In response, Lac-Mégantic Mayor Julie Morin said, “I don’t know if this is happening all the time, but we are looking for assurances from Netflix that … they are going to remove them. You can be sure we are going to follow up on this, and our citizens are on our side.”

At the time of this writing, Netflix has not released an official response.

Directed by Susanne Bier, Netflix's Bird Box is now available to stream and stars Sandra Bullock, Trevante Rhodes, Jacki Weaver, Rosa Salazar, Danielle Macdonald, Lil Rel Howery, Tom Hollander, BD Wong, Sarah Paulson, Colson Baker and John Malkovich.
