The basic story (emphasis on basic and that means really, really basic) was in place. Is in place. Much of getting beyond basic depended on who was playing the lead character.
A few possums tried out. This was the first one.
Reluctantly, I allowed a girl to audition and was pleased to discover that a girl was exactly who the lead character should be.
Unfortunately, the girl who tried out, while right in so many ways, was wrong in the critical ones. You can see for yourself.
I will keep looking.
