Rights issue?

Great concept, but aren't these Hollywood Monsters the property of the studios that spawned them?

You have a very valid point Ryan, however it will be upto the legal department to try and secure the rights/ licesing for those characters, each stuido has a licensing department although it may take a small fourtune to acquire the rights to those properties, since this is somewhat a parody there could be some wiggle room on this possibly, again that would need to be addressed by the rights owners and an entertainment laywer, as far as Dracula is concerned, Count Dracula was a historical figure. Vlad Dracula, or Vlad the Impaler was a man of royalty of some sort (hence the "count").
He lived in a freakish castle in an area of Transylvania, Romania. His freako castle is the legend that we see in scary cartoons, etc.
He was known as Vlad the Impaler because, unfortuneatly, he murdered thousands of people by... well.... impaling them on about 9 foot long wooden shafts he stuck into the ground.
He's gruesome. And he wasn't a vampire. But he is historical figrue so you can't copyright him just like you can't copyright Teddy Roosevelt or Napoleon, bu trust me when it comes to known characters and you want to use them in your script I'm sure someone will come out of the woodwork and try to throw a wrench in the works, when it comes to showbiz that's jst the nature of the beast, again Ryan you have a very valid point on the issue.
