Fans can be assured that many of their favourite cast members are returning for the new episodes. Nicholas Ralph is back as James Herriot, Rachel Shenton is back to play his wife, Helen, and Samuel West is back as Siegfried Farnon.
However, one major character, Tristan Farnon, will not be back after being enlisted to fight in the war. Fans were devastated to learn that Callum Woodhouse would not be back to reprise his role. One person wrote on social media: "Tristan/Callum is part of the magic, please do whatever it takes to bring him back."
