The exec joining me on Doctor Who is Caroline Skinner - fresh from the wonderful Five Days, and still finishing up on a brand new show called The Fades (a fantasy horror series, written by Jack Thorne - I've seen episode 1, and it's BRILLIANT.) Somewhere between me laughing in a basement and choosing planets to invade, and Marcus Wilson raising armies, there has to be a Prime Minister actually running the whole thing. That's the job Piers Wenger and Beth Willis have been doing so wonderfully for the last few years. Now that Piers is off to movie land, that's the furnace Caroline will be walking into.

Following the game-changing mid-series finale in June, The Doctor returns for the first of six new episodes to be broadcast on BBC One this autumn. Matt Smith, Karen Gillan, Arthur Darvill and Alex Kingston star in this new adventure written by Steven Moffat and directed by Richard Senior. Join us for the chance to see this opener to the autumn series followed by a Q&A with some special guests (to be announced nearer the time). We regret that due to the pressures of time, autographs will not be possible.

In 1974 an unknown actor called Tom Baker was cast in the lead role of Doctor Who, and turned an already popular show into a phenomenon. For a generation, the Fourth Doctor is the definite article– warm, witty, clever and sometimes very strange indeed. Clad in his trademark overlong scarf and with a bag of jelly babies to hand, he strode confidently through some of the show’s most memorable adventures. Over seven exciting years this Doctor met old adversaries - like the Daleks, Cybermen and Sontarans –with some help from much-loved friends like Sarah Jane Smith, Leela, Romana and the faithful K-9.

If you’re a fan of the incredible new series of Doctor Who, then this is a great chance to check out where the legend began. If you saw it back in the day then you won’t need reminding what awesome fun it was to go travelling with the Fourth Doctor every weeknight. Get on board the TARDIS and have yourself some all-time classic adventures in time and space with Doctor Who: The Tom Baker Years – only on SCI FI!
