The David Tennant Treat 4 Today is a series of eight videos where David talks about Masterpiece Contemporary, Doctor Who and acting in general.
This was quite a high profile slot for David back in 2012 in America as he was on screen to introduce a series of dramas on the PBS station each week.
Although David looks cool in the clips, apparently he recorded them in temperatures above 30 degrees in a hot TV studio!

Apologies if any of these videos do not play in your country.
