Director Selene Kapsaski used the same film and sound equipment to film London Calling that was used for the feature film Spidarlings (2016)
The pilot episode, featuring Eastenders actress June Brown, was filmed at Molly Moggs Theatre Bar in Soho, London, England.
London Calling was originally broadcast as a segment on US TV in The Xandermonium TV Show (Madrigal Media), hosted by Xander Gibb.
The London Calling title theme was written and produced by Jeff Kristian in his Kent studio, Sparkie's Little Music Factory.
