The Canadian-American time-travel sci-fi drama was recently found to have used footage from the Lac-Mégantic rail disaster that killed 47 people in 2013 in an episode's depiction of a newscast about a nuclear bomb going off in London. On Monday, Peacock Alley Entertainment, the Toronto-based production company behind the series, apologized and said they would be “replacing the footage in the show," which it said was purchased from an archival footage service. “We sincerely apologize and had no intention to dishonour the tragic events of 2013,” Carrie Mudd, president of Peacock Alley Entertainment, said in a statement sent to The Washington Post via a Netflix representative.
