It is hard to know which is more unlikely, a horror film on Twitter or that movie being set in South Croydon.

But Kiwi screenwriter and film maker, Kristi Barnett, is today launching what is claimed to be the first ever Twitter horror flick.

For the next three weeks she will be tweeting out a creepy story via a live character on Twitter called KarenBarley. The 3 week event will have videos, photos, audio and links before ending in a climactic video.

The film is set in Croham Hurst, South Croydon, near where she lives.

The main character, Karen, is convinced by her sinister boss to take on an outdoors project in an ancient Bronze Age woods in Surrey. Her boyfriend Darren is excited about the mysterious legend of the Hurst and can’t wait to find a hidden path he’s heard of.

On first appearance the Hurst seems mundane, with traffic and people close by. But gradually they begin to experience strange sounds and druid like signs. When Darren discovers the path, he opens a portal that lets in his Other.

Convinced that her boyfriend is trying to frighten her, Karen slowly spirals into a deadly paranoia that result in tragic consequences. And all the while her madness is played out for all to see as she uses Twitter to tell everyone “what’s happening”.

Kirsti Barnett says: “This is an experiment in storytelling that has not previously been done. Let’s show all the struggling writers & filmmakers who are trying to get their stories seen and heard that there is a way to push through the gates. I hope they’ll use our example to try it themselves”.
