Episode 8: Let's Kill Hitler
Written by Steven Moffat

The gang's all back! The Doctor, Amy, River and Rory return in what promises to be an action-packed belter of an adventure. So far the following details have emerged:

'In the desperate search for Melody Pond, the TARDIS crash lands in 1930s Berlin, bringing the Doctor face to face with the greatest war criminal in the Universe. And Hitler. The Doctor must teach his adversaries that time travel has responsibilities - and in so doing, learns a harsh lesson in the cruellest warfare of all.'

We also know it features Albert Welling as Hitler and is directed by Richard Senior, previously at the helm for Time and Space plus the Doctor Who pre-title sequence for this year's NTA awards.

Episode 9: Night Terrors
Written by Mark Gatiss

Mark Gatiss has previously written spooky episodes including The Unquiet Dead and The Idiot's Lantern, but he promises that Night Terrors features some of the scariest moments he's ever dreamt up! The adventure has a modern day setting and features a little boy who has a fear of something... Can the Doctor help him?

Episode 10: The Girl Who Waited
Written by Tom MacRae

Tom MacRae's previous credits include The Rise of the Cybermen/The Age of Steel plus the critically acclaimed The Crash of the Elysium. This is his first television adventure for the Eleventh Doctor and it's directed by Nick Hurran who was recently at the helm for the updated version of the cult classic, The Prisoner.

Episode 11: The God Complex
Written by Toby Whithouse

We know the adventure is set in a hotel and features an alien called Gibbis played by David Walliams. Again, the episode is directed by Nick Hurran and as writer Toby Whithouse was behind School Reunion and The Vampires of Venice, we know we've got something special to look forward to!

Episode 12
Written by Gareth Roberts

Craig Owens is back! The popular character from last year's The Lodger returns and judging from the trailer for eps 8-13 he's getting closer than ever to the Doctor! The adventure is written by Gareth Roberts whose credits include Attack of the Graske, The Unicorn and the Wasp and, of course, The Lodger.

Episode 13
Written by Steven Moffat

The big finale! This one remains shrouded in mystery but Karen Gillan has promised us that the series will contain 'possibly the biggest twist so far'... Is it possible that this is the adventure that delivers it? Steven Moffat penned last year's incredible finale but it's probable that this adventure will conclude the series with a bigger bang than ever!

It’s looking like this series is going to one of the best ever! What are your thoughts on it based on what we’ve heard so far? Let us know below!
