Doctor Who: 14 Cool Details Revealed In David Tennant's The End Of Time Part One Commentary
6. This House Location Was Used In The Unicorn And The Wasp
It's impossible to talk about a Doctor Who episode without discussing reused filming locations, and The End Of Time Part One is no different.
Just past the halfway point in the commentary, Tennant mentions that the Naismith mansion scenes were filmed at Tredegar House in Newport, Wales, and in addition, he points out that the room seen behind Naismith and his daughter in the above shot is the same room featured in The Unicorn And The Wasp's dinner scene.
Note the small stone statue next to the window in both images.
Tredegar House has been used in lots of other Doctor Who episodes - such as Tooth And Claw and The Girl In The Fireplace - and it's mentioned later in this commentary too, which we'll get to quite soon.
