6F. Doctor Who - Mawdryn Undead

Season Twenty

Script Editor: Eric Saward; Produced by: John Nathan-Turner; Writer: Peter Grimwade; Director: Peter Moffat; Designer: Stephen Scott; Incidental Music: Paddy Kingsland;

At a public school in England, 1983, a school-boy prank goes drastically wrong: Two boys take the Brigadier's classic car for a spin, but end up driving it off the road to avoid a collision. Both are thrown clear. It is at this time that the Black Guardian takes the opportunity to recruit Turlough to the task of killing the Doctor.

Meanwhile the Doctor quickly materialises the TARDIS on board a ship stuck in warp drive to avoid a collision. The Doctor finds a transmat device, and beams down to Earth whilst Nyssa and Tegan follow in the TARDIS. However, whilst the Doctor arrives in 1983, Tegan and Nyssa arrive in 1977.

In 1977 they find a person with serious injuries in the transmat capsule and believe it to be the Doctor suffering from a regeneration. Tegan seeks help, and finds Brigadier Lethbridge-Stewart. At the person's behest they return to the warp craft. In 1983 the Doctor finds Turlough, and a later version of the Brigadier. He tells the Doctor what happened during 1977, but something made him lose his memory. The Doctor, along with Turlough and the later Brigadier, returns to the warp craft.

There they find seven people who tried to turn themselves into Time Lords and have condemned themselves to eternal agony. The Doctor reluctantly offers to help, although it would mean he could no longer regenerate as each remaining regeneration would be used to end a life. However, at the point of transference of energy the energy didn't come from the Doctor, but from the two Brigadiers when they met. The people finally die, the Brigadiers are returned to their time streams. The ship explodes, and everyone wonders where Turlough is, until they find him in the TARDIS.

Bloopers and mistakes

Episode 1: When the Doctor and Turlough are about to leave the TARDIS to disable the T-Mat signal on Earth, the Doctor has to hold the red door lever up, because it wouldn't stay in the "door open" position. Every time Peter Davison tried to move his hand away, it would start sliding back, and he'd have to hold it again.
