Speaking to Radio Times in an exclusive look back at every Tardis design since the series began, Tennant mostly had warm memories of his years at the helm – though he admitted there was one slight design flaw that made filming the series a bit trickier than you might imagine.
“There’s something very pleasing about stepping out of that iconic box wherever it might land,” Tennant tells Radio Times in our latest Tardis-themed issue, “but with the actual box itself it was always quite hard to close the door, because it was flat-packed.
“It would be assembled usually rather quickly – and very expertly of course – but sometimes, like any Ikea cabinet, the doors weren’t always as flush as they might be when you were making a big exit or entrance.”
In other words, sometimes as the Tenth Doctor made his escape from evil forces, burst dramatically into a scene to save the day or just waved a sad goodbye to an old friend, he then spent a good few minutes furiously trying to jam the door closed, rather undercutting the dramatic heft of the scene (and requiring some judicious re-takes and smart editing).
