Sceneggiatura Bob Baker – Interpreti William Hartnell, Jon Pertwee, Patrick Troughton
To celebrate the tenth anniversary of the launch of the series, writers Bob Baker and Dave Martin concocted this four-part special that united the current Doctor Who (Pertwee) with his two earlier selves, William Hartnell and Patrick Troughton. The Doctor calls on the Time Lords for help when his companion, Jo Grant, are attacked on Earth by a plasma-like creature. However, as they are under attack themselves, with their energy being drawn off into a black hole, the Time Lords despatch to Earth the Doctor’s two earlier incarnations to aid him in his defence against the creature. Owing to Hartnell’s illness (this would be his last acting role prior to his death in 1975), his Doctor character was caught in a time eddy and is only relatively briefly seen on monitors throughout the story, thus enabling the actor to perform all of his scenes while seated. The greater part of the story was thus devoted to the remaining two Doctors, and provided a welcome opportunity for viewers to become reacquainted with Troughton’s mischievous, impish characterisation.
