I wish they would make a series out of this movie.
The concept surely has a good potential.
It can take place almost anywhere and in any time.
In the movie they show a bunch of creatures.
Here are the ones who are on the betting board.
I'm not sure if those are all of them.
Anyway, the ritual happens in several places all over the world.
So I think it's safe to assume every location has it's own collection of monsters.
