OK, Hollywood, I have another blockbuster idea for you.
An Andy Taylor prequel where we visit his military career in WWII. Wikipedia states that some of the years listed by the writers don't exactly line up with the actual war but that there are references to him being stationed in France and in N Africa as a first sergeant.
What I'm thinking is N Africa where Andy finds himself battling zombie mummies in caves.
Maybe he could meet his wife, a rough & tumble archaeologist who belly dances. That would explain her having no family in Mayberry.
This will work, Hollywood. I will wait.
