Today, in Forbidden Planet Megastore on Shaftesbury Avenue in London, Doctor Who/Sherlock/Dracula producer Sue Vertue popped by with her husband and writer/showrunner of all those shows, Steven Moffat, to do a little signing of Titan Comics' Sherlock manga publications, that adapt the original scripts of the show in excruciating detail for manga readers in Japan, and have now been retranslated back into English.

A small crowd was waiting for the pair, as Forbidden Planet, also part of the Nick Landau/Vivian Cheung media empire as Titan Comics, had only been able to announce the signing mid-week. But it was soon topped up by casual shoppers unable to believe their luck that The Moff had lowered himself to appear among mortals.

Their Dracula is set to hit British TV screens on BBC 1 on New Year's Day, to follow the new Doctor Who. It will then be available internationally on Netflix from January 4th. I'd say to watch out for spoilers, but you know, it's based on the book which was published quite some time ago.

Moffat and Vertue entertained attendees well past their allotted slot and also signed a bunch of Sherlock manga box sets which Forbidden Planet will be selling in store and via mail order.

He also mentioned that as well as working on Dracula, an adaptation of The Time Traveller's Wife for HBO – a book that did a lot to inspire River Song in Doctor Who, and a new drama about death row called Inside Man for the BBC, he is also writing a play – though he can't say anything about that yet. So he didn't. But this would be the first time he has been a playwright, so I look forward to finding out more next year.

I also took the geeky chance to ask the both of them if anything had happened with a planned Bruce Willis-attached movie from a couple of decades ago, a comedy thriller called Me Again. No plans, it is still sitting in a drawer and he says that if he ever revisited it would need some heavy rewriting, but hey, if anyone with any clout who is reading wants to look at an unmade Steven Moffat screenplay – first draft at least – it is sitting there.

You can find signed Steven Moffat Sherlock comics right here – there's still posting time for Christmas.
