Here's a unique experience from September 1990..... "Ghosts, psychopaths, vampires and the 'undead' - which of them will make our flesh creep into the year 2000? Six fevered imaginations from the world of fear gather together at the Horror Cafe to discuss what frightens them and to create the ultimate dark fantasy. With the directors John Carpenter (Halloween), Roger Corman (The Fall of the House of Usher), Clive Barker (Hellraiser) and the writers Ramsey Campbell , Peter Atkins and Lisa Tuttle." (from BBC Genome) But did they anticipate the audience of the 21st century might be most horrified by the sight of them lighting up around the table.......

I’ve focused a bit too much on films here, so thought I’d throw in something on British horror books and Clive Barker seemed a bit too obvious, so I was fishing for some kind of documentary on Ramsey Campbell and found this, which also includes Clive Barker as well as Peter Atkins (wrote Hellraiser 2) as well as American horror luminaires. Oddly all three British guys were born in Liverpool. Not sure what to make of that, for now.
