The twenty-third season of British science fiction television series
Doctor Who, known collectively as The Trial of a Time Lord, aired in
weekly episodes from 6 September to 6 December 1986. It contains four
adventures: The Mysterious Planet, Mindwarp, Terror of the Vervoids
and The Ultimate Foe. The season marks Colin Baker's final regular
appearance as the Sixth Doctor.The idea for the serial stemmed from
several production changes to Doctor Who, such as reduced screen time
for the season and an instruction from BBC1 controller Michael Grade
that the series needed to contain less violence and more humour.
Several problems occurred during production, including the death of
scriptwriter Robert Holmes and the resignation of script editor Eric
Saward. When it ended, Baker was dismissed from the role on the orders
of Grade.In the serial, the Sixth Doctor is tried by the High Council
of Time Lords for breaking several of the laws of Gallifrey, the Time
Lords' home world, including interference with outside worlds and
genocide. A mysterious character called the Valeyard acts as
prosecutor. In the first two chapters (The Mysterious Planet and
Mindwarp) events from the Doctor's past and present are submitted as
evidence of his guilt. The third chapter (Terror of the Vervoids)
presents future events in the Doctor's defence. In the concluding
chapter (The Ultimate Foe) the Doctor's trial is halted, and the
Doctor confronts the Valeyard and his old rival, the Master, in order
to clear his name and to save the High Council. Doctor Who (season 23) Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
