David Tennant’s video diary continues

It’s cold outside, there’s no kind of atmosphere: yes, DT is back in Britain for his latest video diary – this time, in glorious HD. Facts we didn’t need to know: Michelle Ryan enjoys pain and being hung upside down from a harness. Thanks DT.

But in advance of watching the video, would anyone want to hazard a guess as to why he latched on to the third assistant director for a chat?
