EastEnders will air their one hour Halloween Special in only a couple of days and writer Leo Richardson has revealed that he had many of Hollywood's iconic horror films in his head when writing the episode.
"But most of the references to Scream, Friday the 13th and A Nightmare on Elm Street are all still in there somewhere.
"Kathy is basically the Scream Queen in her own horror movie."
In the past, we have seen Abi stalk her sister, Janine murder her husband Michael Moon, this year many characters will have turning points in their lives.
Executive producer Dominic Treadwell-Collins said: "Our Halloween episode kicks off a lot of big things. There's lots of stuff for Sharon, for Phil, for Stacey and Martin. A lot of things are kickstarted in this episode.
"What you'll see is that Kathy and Phil have both been given panic buttons and everyone thinks that Gavin has gone. But of course not!"
Gillian Taylgorth who plays Kathy said: "It was wonderfully written, it was fantastic," she told Huffington Post of her experience making it. "Paul Nicholas [who plays Gavin] has turned into this tyrant!
"He was fantastic. He’s got such a charming smile but he can be really menacing. He loves it – he’s never played anything like that.
"He’s really gone for it and it’s a joy to behold.”
The Halloween special of EastEnders airs on Friday at 7:30pm on BBC One.
