My lifelong dream has been to adapt "Mommie Dearest" as a musical. Then I found out someone already did that, and it was a huge flop. If ONLY I had gotten there first! "No More Wire Hangers" would be the eleven-o-clock number and the counterpoint between Christina and Joan would have rivaled anything from Les Mis.
Here are a few others on my list for possible stage adaptations:
The Hills Have Eyes
Slumber Party Massacre 3
A really upbeat version of "The Passion of the Christ"
Drop Dead Gorgeous (this would make such a fucking fantastic musical and I have dibs on the Brittany Murphy character)
The original Scream
Eyes Wide Shut
Doubt! (with explanation mark, of course)
I just don't know which one to start with.
