Four years after its "official" demise as a weekly series,
Doctor Who briefly resurfaced in the form of a two-part, off-length special. Created to celebrate the 30th anniversary of the series' birth, "Dimensions in Time" was shown as a component of two other TV programs. Part One aired November 26, 1993, as an eight-minute segment of the BBC's Children in Need Telethon. In this installment, five of the Doctor's seven incarnations -- played by surviving series stars
Jon Pertwee,
Tom Baker, Peter Davison, Colin Baker, and Sylvester McCoy -- were pitted against renegade Time Lady Rani (Kate O'Mara, likewise repeating her
Doctor Who role), who hoped to determine the outcome of the universe's evolution. This cliffhanger would be resolved the following evening on the series' Noel's House Party. Featured in the cast were several of the Doctor's former "companions," including Nicola Bryant (Peri), Sarah Sutton (Nyssa), Sophie Aldred (Ace), Carole Ann Ford (Susan), Elisabeth Sladen (Sara), and Bonnie Langford (Mel). "Dimensions in Time" was written by John Nathan-Turner and David Roden. ~ Hal Erickson, All Movie Guide
