Idea for Sequel (Spoilers)
Ok so dont read on incase you don't wanna know the ending.
This is just my vision I had for a sequel, after watching the film.
I think a sequel could easily happen, if they ever decided to do one for the fans. First of all, I don't think it would work without Shannon Elizabeth coming back as Angela. She was awesome and I think she did a kick ass job for the scenes she had. Angela should have a much bigger role. She is the queen of demons now. How it would start is after maddie escapes the house, I was thinking that maybe the two sound guys go inside and find the bodies. They end up fooling around and someone gets cut by something, and his blood just so happens to splash inside Angela's skeleton's mouth., afterall they needed human flesh/blood to feed. She is revived after they leave. But she's the only demon alive now and can't leave until 6 more souls enter the house. Fast forward 2 years later, Halloween Night. Maddie is still sort of grieving over her friends' deaths and in doing so, she has found herself a new job. Demon Hunting. Now skip to Colin's russian drug dealers. Why? They are convinced Colin booked town a year ago, and he isn't quit over his unpaid debt. It's alot of money. So with no Colin to kill, they want Maddie. Maddie happens to pay a visit to the brousarrd mansion, and sees a bunch of kids heading into the abandoned building. Worried so, she follows to see how many-- it's six. Shes relieved (because she is unaware of Angela being alive)... until moments later- Angela leads out a pack of fresh demons. Maddie books it so Angela dosn't see her.
Angela and her minions reak major hell on the city of New Oreleans at this point. She even grabs herself a new, bad ass/sexy Halloween costume. Her plan is to take the city over and posess everyone into demons and eventually spread her evil influence throughout the world. Colin even comes back and looks for Maddie too.
Maddie heads to a nightclub to grab her younger brother so they can hurry and leave town... until she notices Colin's drug dealer and the blonde bitch with the gun are there and looking for her. If things couldn't get any worse, Angela arrives and starts doing her little dances on stage and sort of glamouring everyone into a trance. Demons then attack everyone and more and more produce.
Maddie and her brother escape with the drug dealers. Maddie figures that killing Angela is the way to stop all of the demons. She is the queen B afterall.
After battling through a New Orleans full of Demons, Maddie kills Angela and her soul/body return to Broussarrd Mansion- unbeknownst to Maddie though of course, so a third one could be set up (just incase)
Anyways, that's just a little rough-outline I did for it. If a sequel were to get made, what would you wanna see?
