Appearances Television During rehearsals for their first appearance, Kevin Lindsay, who portrayed the original Sontaran, Linx, pronounced the race's name as "son-TAR-an." Alan Bromly, the director, tried to correct him by saying it should be pronounced with the stress on the first syllable. Lindsay declared "Well, I think it's "son-TAR-an", and since I'm from the place, I should know." His preferred pronunciation was retained.

In "Turn Left" (2008), the same events are depicted in a parallel universe, where Rose Tyler (Billie Piper) describes their plan as foiled by Torchwood (characters from the spin-off show of that name), at the cost of their lives, with Torchwood leader Captain Jack Harkness (John Barrowman) being captured by the Sontarans.
