This excerpt from “42”, running a little over a minute and a quarter and starting eighteen seconds into the clip, was shown during an interview with David Tennant on “Parkinson” and broadcast later the same evening as “The Lazarus Experiment”. The sequence certainly sends a chill down the spine as Martha becomes irrevocably separated from the Doctor! I thought it better than anything seen in the complete episode aired earlier that night!! I’m not biased or anything but “42” is directed by Graeme Harper!!!
