We all know what takes place in the 31rst of October night. It's the most terrifying night of the year, Halloween, a Celtic party which takes place in English countries as Canada, USA, Ireland or United Kingdom, and, to a lesser extent, in other places as Spain or Latin America.  The day is associated with the orange, black and purple colours, and it's linked to symbols as “jack-o'-lantern” which is a carved pumpkin where the top of it is cleared away as a lid, and then the pulp is removed; over its surface, a monster face is carved. During the night, a candle is placed inside of it to create a terrifying effect.

It is also common costumes parties, haunted houses, bonfires, histories, horror movies, and the very famous "Trick-or-treat". It is an activity where the children go from house to house asking for treats such as candy with the phrase "Trick-or-treat" (Where the owner of the house is threated with a joke in case candy is not provided).

But there are many more curiosities about this celebration that many people don't know: For instance, the word “Halloween” is a contraction from "All Hallows Eve", apparently, because this English ghoulish and humorous celebration is related to a solemn, and considered as strict adherence by the Catholic church: the 1rst of November.

As I said before Halloween has Celtic origin, 3000 years ago. The Celtic villages in Ireland, Wales, Scotland and North of France, celebrated the Samhain (which means "the end of the summer") and which took place at the end of October and beginning of November. A rite in the end of the harvest was celebrated and the beginning of the winter. The druids believed that night 31rst of October as the one where the limit between the world of the dead and the living world disappeared, and the witches had more vitality. They even thought that the ghosts of dead people came to the living world to bring people to their world. That's why in the Samhain night, the druids prepared bonfires and spells to chase bad spirits, and people leaved candy and food in the door of their houses, with the superstition that the deceased, will go away and leave them alone.                    When the Christianity arrived at the Celtic villages, the Samhain tradition doesn't disappears, but it changed in spite of the effort of the Catholic Church for eliminate pagan superstitions which could draw with the Satanism or adoration to the devil. In the Gregorian calendar, the 1rst of November became all Saints day, and Samhain, became the “All Hallows Eve”, currently “Halloween”.

As expected, this curious celebration has had a very strong impact in the cinema industry. We can find from the most terrifying movies: such as "Halloween", "I know what you did last summer", "Saw" or "Scream" sagas, to more sympathetic films as my favourite director Tim Burton: "The nightmare before Christmas", "Frankenweenie", "Corpse Bride", "Edward Scissorhands", "Sweeney Todd" or "Sleepy Hollow".
