The British Film Institute have now made parts of the Q&A panel with guests at the screening of An Unearthly Child on 12th January available to watch via their YouTube channel.
The first, nine minute segment from before the story was shown features a chat with the story's vision mixer Clive Doig and special sounds creator Brian Hodgson, alongside writer/actor Mark Gatiss (writer of the 50th Anniversary drama An Adventure in Space and Time). The second, fifteen minute segment features a cast and crew discussion after the showing, with Waris Hussein (director), William Russell (Ian), Carole Ann Ford (Susan), Jeremy Young (Kal), Donald Tosh (writer/script editor), and William Hartnell's granddaughter Jessica Carney.
The next (sold out!) event takes place on 9th February with the Second Doctor celebrated by a showing of The Tomb of the Cybermen (guests to be announced).
