Stars of cult British sci-fi series Doctor Who, including current Time Lord Matt Smith, are hosting special talks for fans next year (13) as part of the show's 50th anniversary celebrations.

British Film Institute (Bfi) bosses are planning a series of events for the Doctor Who At 50 tribute, to be held at the Bfi Southbank in London throughout 2013.

Actors who have played the title role, including Smith and William Hartnell, will chat with devotees at monthly question-and-answer sessions, rare footage will be screened, and a preview of Doctor Who writer Mark Gatiss' new drama An Adventure In Space And Time will also be unveiled in November (13).

Doctor Who executive producer Caroline Skinner says, "To be doing this enormous and exciting project with the Bfi is just a dream come true. We're delighted that in this 50th year for the show we have such brilliant support from the Bfi for our celebration of Doctor Who's cultural heritage. Some of the stories we're going to show are thrilling, surprising, funny and just plain classic Tv."
