Two things:
1. If the Halloween maze is really just a "best of", which movies in the franchise would be represented? Isn't the thing with the Halloween franchise that there are various IP owners, that it's complicated to get rights to different movies, sort of like how the rights for Scream and Hellraiser are all over the place?
2. Worst case scenario for Halloween is that it goes the route of Titans of Terror, where they continue to story of the Uber Fan, now having a nightmare about Michael.
3. Just to verify, when we say IT is going in 747, we're talking about the queue and not the Sound Stage, right?
