Jonathan Forbes

Jonathan Forbes played Trevor Gale in the audio story Night of the Stormcrow, Dr Sturgis in The Great War, Patrick O'Sullivan in Tangled Web, Kurt Schalk in Persuasion and Daleks Among Us (although he was credited as playing Lukas Hinterberger in both stories), Barry Finnegan in Afterlife, Heff in Tomb Ship and Walter Vincent in Rule of the Eminence.
