In the 2015 James Bond movie, Spectre, the opening sequence features a Day of the Dead parade in Mexico City. No such parade ever existed, but due to the interest in the film and the government's desire to promote pre-Hispanic Mexican culture, the government organized an actual Día del los Muertos parade for the following year.
Halloween in Mexico, called Día de las Brujas, is the beginning of the Days of the Dead festivities.
The day of the innocents, also called Day of the Little Angels, is specifically dedicated to people who died as children.
The Day of the Dead is the final and most popular day of the three day long celebration.
