What I found very interesting about this retrospective is some of the open opinions regarding the Director and the character of Adric and also the interpretation of Beryl Reid. It was very refreshing. To think that this was shot in six days is incredible. Have to tip your hat to Peter Grimwade, who despite the tensions amongst cast, pulled out a tight little thriller and created one of Peter Davison's best stories. The only person missing from this is Janet Fielding. A shame as it was great to hear from all of the others and see how they look now (well, 2003) and how they felt about their involvement. A must watch for any classic Dr Who aficionado.
