The film was shot in Hereford, birthplace of Frank Oz. It stars Pat Garrett, who was Kermit the Frog's legs in The Muppet Christmas Carol.
The Wyvern folklore the film invests in states that when the Wyvern was first found, it was the size of a cucumber.
The production crew had arranged for a furnished cottage ready for filming but on arrival they realised that not only the cottage had no furniture, it also had just been painted white and had had new carpets fitted. This became a production issue as walls and carpet had to be protected at all times from blood stains and other bodily fluids.
The film was shot in September 2020, in the midst of the COVID 19 Pandemic, between two lockdowns in 25 consecutive days.
The film won Beat Feature on its premiere showing in York.
