When the social distancing and lockdown measures of 2020 all but halted global film and television drama production, a thought occurred to the team at Century 21 Films. While more conventional dramas with human casts and vast crews now posed a logistical nightmare to all involved, the heroes of Supermarionation hold no risk of  coughing or sneezing on one another! In this very strange time, the decision was made to see what sort of "Superisolation" production could be put together under these extremely odd circumstances. The result is NEBULA-75, a short-form puppet drama that follows in the tradition of 1960s favourites while offering something brand new at the same time .

Although team members from around the world contributed remotely to pre and post production, the entirety of the filming for NEBULA-75 was undertaken by a crew of three who happened to already live together in a small flat in London. Their living room was transformed into a makeshift movie studio – with bookshelves, cardboard boxes and other household objects becoming the interior of the show's hero spacecraft. This flat was  also fortunately home to many of the puppets, props, and costumes that have been accumulated over the course of different productions.
