A David A. McIntee penned Zygon film was in the works at BBV Productions circa 2003, written at the same time as Zygon: When Being You Just Isn't Enough. It was “kind of a Faustian thing about their shapeshifting ability, and people wanting to get that.”
The script for the film was written, but Bill Baggs told McIntee the film wouldn't be made and didn't pay McIntee the remainder of the money owed to him for completing the script.[1]
