Doctor Who: Timelash

The TARDIS gets caught in the Timelash, a powerful time corridor that brings the Doctor (Colin Baker, the sixth Doctor Who) and Peri (Nicola Bryant, Holby City) to the troubled planet of Karfel. The planet is on the brink of war and ruled by an insane and much-feared dictator, who punishes Karfelons by throwing them into the Timelash. But why is their leader never seen in person? The Doctor arrives just in time to find out. As seen on PBS. Extras include audio commentary by actors Colin Baker, Nicola Bryant and Paul Darrow; The Good, the Bad, and the Ugly, a new "making-of" documentary; and a photo gallery.

On the planet Karfel a high ranking official, Maylin Tekker, uses threats against Peri to force the Doctor to go to Earth and bring back a young woman called Vena who, while holding a precious amulet, has accidentally fallen into the Timelash - a time tunnel through which the planet's tyrannical ruler the Borad banishes all rebels. The Doctor also inadvertently brings back Herbert, a man from the 19th Century, who stows away aboard the TARDIS.
The Borad was once a Karfelon scientist but accidentally sprayed himself with an unstable compound called mustakozene-80 while experimenting on a Morlox - a savage underground reptilian creature - and consequently became half-Karfelon, half-Morlox.
The Borad plans to bring about the deaths of all the Karfelons by provoking a war with their neighbours, the Bandrils, and repopulate the planet with creatures such as himself, starting with Peri. The Doctor uses a kontron time crystal to defeat a clone of the Borad and makes peace with the Bandrils. He then defeats the real Borad by banishing him through the Timelash to 12th Century Scotland.

A major source of inspiration for this story were the works of novelist H G Wells.

Paul Darrow, better known as Avon in Blake's 7, plays Tekker.

Denis Cary plays the face of the Borad. Cary had previously played Professor Chronotis in the abandoned season seventeen story Shada and the Keeper in season eighteen's The Keeper of Traken.

A mural of the third Doctor's face is revealed behind a section of wall panelling in the Timelash control room; this painting, supposedly a legacy of a previous visit by the Doctor to the planet Karfel, was actually the work of American fan artist Gail Bennett.
