The Laird of McCrimmon (unproduced TV story)

✅ The Laird of McCrimmon was an unmade Doctor Who serial written by Mervyn Haisman and Henry Lincoln. It would have aired during Season 6 and would have featured the Second Doctor, Jamie McCrimmon and Victoria Waterfield, who in actuality departed during the previous season. The story, a candidate for Frazer Hines' departure story, was abandoned in August 1968 due to a dispute which arose between the writers and the BBC regarding the copyright of the Quarks, who made their first and only televised Doctor Who appearance in DW: The Dominators, notwithstanding a brief cameo in DW: The War Games.

The storyline would have involved a possessed Jamie piloting the TARDIS to 1746 Scotland and his ancestral home, Castle McCrimmon, at some point after the Battle of Culloden, the aftermath of which was depicted in DW: The Highlanders. There, he finds the current laird, Sir James McCrimmon, on his deathbed. Yeti appear and surround the castle where the local villagers fall under the influence of the Great Intelligence. The only person who seems to be immune is a girl named Fiona, with whom Jamie falls in love. The Great Intelligence wants to inhabit Jamie's body and become the laird once Sir James dies. However, the Intelligence is ultimately defeating by the Doctor. Jamie decides to leave the TARDIS and become the laird himself.

Given the acrimony between Haisman and Lincoln on the one hand and the BBC on the other hand, the Yeti - who had previously appeared in their earlier serials DW: The Abominable Snowmen and DW: The Web of Fear - never again featured as the major antagonist in a televised Doctor Who serial. However, a Yeti made a cameo appearance in DW: The Five Doctors, the series' 20th anniversary special.
