Another radio show that got a pilot as part of the Comic Asides strand on BBC Two was And Now, In Colour. Only here it was called It’s A Mad World World World, and was completely re-cast, but written by the original crew.
This wasn’t the first TV pilot for the radio show though. A non-broadcast pilot keeping the original title and cast was made, again by Pozzitive. It was produced by David Tyler, and directed by Simon Spencer. Some of the script for the second pilot is available on Pozzitive’s site here, under Extras.
