There's no real reason for my choices, they're just the first thing that comes to mind:
Doggett - Peter Pan, Childish and wants to live in a fantasy world.
Circus - Ted Logan (Bill 'n' Ted)...Nuff said.
ghouck - Dr. Peter Venkman (Ghostbusters)
Sister Grace - The Thing, sometimes she's one thing, othertimes something else...
Paquita - Ed (Raising Arizona), She's adorable and I just want to give her a big hug.
Newt - Red Sonja, I have no idea !!!! Your guess is as good as mine ?!?!
Cheezeflix - Quint (Jaws), just seems like that sort of a guy.
The Rev - Batman, this board is his Gotham City. He protects us.
I'm sure I'll post more later.
They really don't have to make any sense.
Newt as Red Sonya ?!!!!!?!?!
