In October 1991, Universals latest horror release was little-loved sequelChilds Play 3: Look Whos Stalking.

The first event (see clips from ithere) was predominantly a collection of live shows on outdoor stages.

Attendees were terrorised by the likes of burly actors inThe Thunderdomeor a Michael Keaton-wannabe inBeetlejuices Graveyard Tours.

The days of scare-actors as theyre now known bringing in home-made costumes are also firmly in the past.

We have people in the event who have worked all twenty-four years of Halloween Horror Nights.

We have individuals that literally take vacation from September to the beginning of November just to work the event.

Aiello has first-person experience not only of casting those actors, but being one too.

I jumped out of a washing machine eighty times an hour, he remembers.

Now he heads up the team designing each maze and conceiving new methods of unsettling the visitors inside them.

Each house is a choreographed ballet of misdirection and surprise.

Ive seen people lose their facilities, says Aiello.

This year, with theHalloweenmaze, were finding there are two rooms that people literally will not go in.

They literally stop and you see this jam that occurs, they dont want to go any further.

Theyre literally pushed by everyone else saying just go!.

If hes exaggerating, then its not by much.

Aiellos answer is a simple one.

Its not all about fear, he explains, its also a question of fun.

Horror is a very visceral and communal activity.
