Jacob Keith

Jacob Keith voiced Sabbath Dei and the War King in the 2021 Faction Paradox audio story Sabbath and the King, also playing the latter in the story's accompanying webcast Overture to 'Sabbath and the King'. The parts had previously been played by Saul Jaffe and Philip Madoc respectively.

For the release of Sabbath and the King on the BBV website, Keith was credited as J. Stoker Hakewing, an anagram of "the War King's joke" and a nod to a pseudonym once used for Anthony Ainley to conceal his return as.

In 2022, Gary Russell, as part of an online discussion with Keith, joked that the of the Master who was executed at the beginning of the TV Movie (actually played by the Canadian actor Gordon Tipple) was "the awful Maryland version, the 'Jacob Keith' Master". Russell clarified that he was indeed simply joking, and that he did not want it to become "fact" in "five years' time" that he had "said something stupid".

Keith created the composite image of a young Paul McGann used in the trailer for the Big Finish box set The Stuff of Nightmares, a fact endorsed by Rafe Wallbank.
