Midnight ★★★★

Cast
The Doctor – David Tennant
Donna Noble – Catherine Tate
Sky Silvestry – Lesley Sharp

Writer Russell T Davies
Director Alice Troughton

Psychological thrills abound when a tour vehicle breaks down on planet Midnight. An invisible entity possesses passenger Sky Silvestry, who repeats all the Doctor’s words, then speaks them simultaneously, then says them before he does – a technical challenge well met by Lesley Sharp (Sky) and David Tennant. Also aboard: David Troughton, Lindsey Coulson and Colin Morgan (Merlin).
