As BBC America works its way through the history of the various Doctors – while working its way towards the show’s upcoming 50^th anniversary in November – it’s now up to The Seventh Doctor, the title of tonight’s special. It’s a profile of the incarnation of the Doctor played by Sylvester McCoy, who embodied the doctor for a brief run from 1987 to 1989. The tribute also includes a taste of Doctor Who episodes of the McCoy vintage.
