Season 27 (Doctor Who)

Season 27 of Doctor Who ran from 5 September 1990 and 5 December 1990. The season was the final season for both Sylvester McCoy and Sophie Aldred, and introduced, not just, new companions, Katie Tollinger (Julia Sawalha) and Henrick (John Banks), but also, the Eighth Doctor, Richard Griffiths, in the final moments of its last episode.

Departure
In December 1989 after Season 26 finished airing, producer John Nathan-Turner and script editor Andrew Cartmel announced their departures from the show in Season 27, with Sylvester McCoy and Sophie Aldred also announcing their departures after the following season.

The new companion
Early on, an outline was put in place for the new companion to replace Ace. The idea was that the new companion would go by the name of Katie Tollinger, a posh upper-class cat burglar. Julia Sawalha was cast for the role.

Stories
In late 1989, Cartmel commissioned the four stories; all of which were the stories to be featured in the season. They included the likes of: the Doctor and Ace in different manners, the return of the Ice Warriors, a masterplan from the Doctor as well as the introduction of Katie, and a regeneration story featuring UNIT.

Another new companion
A later addition to the season would be another new companion named Henrick (the character's full name is Benjamin Henrick). Played by John Banks, he joins the TARDIS team at the end of the season and into the next along with a new Doctor.
