At the invitation of the University of Hull, Century 21 Films recently presented a Supermarionation workshop as part of the institution’s Arts in Isolation programme. Nebula 75: A Day of Puppets saw Stephen La Rivière, Andrew T. Smith, Elliot Pavelin, and Geraldine Donaldson host an episode screening, conduct a Q&A, and set up and film a scene live on stage that demonstrated the production methods employed for their isolation-inspired adventure series.
