Re: Early version of An Unearthly Child scripts found + others
I wonder: is there a outside chance that the Marco Polo film cans might actually be copies of the Canadian TV series that John Lucarotti had earlier written, and used as the basis for his Doctor Who script (obviously they're not the Doctor Who serial, or that would be the big news).
As for Big Finish versions.. forget about it: on the report at the top, these are earlier versions of scripts which either made it to the screen (An Unearthly Child) or have already been done by Big Finish (The Masters of Luxor).
