Question: At first, the football team doesn't realise that they died. So why do they think that Juno is their coach?
Answer: Right before the Maitlands walk in, one of the football players asks, "coach, where's the men's room?" After which Juno finally loses her cool and dismisses the team out the door. After Juno's conversation with Adam and Barbara, one player comes back in and says, "Coach I don't think we survived the crash" suggesting they realised they were dead.
Question: When Barbara and Adam change their faces and are ready to go scare everyone, Barbara confesses to Adam that she doesn't want to go through with it. She says that she wants to be with Lydia. Why does she suddenly become infatuated with wanting to be with this girl whom she hardly even knows? It would make more sense if they both grew to love the whole family instead of just Lydia alone. Thus, her sudden change of heart seems kind of strange.
Question: After Otho and the Deetz family are attacked by the Beetlejuice snake why do they stay in the house instead of fleeing immediately?
Answer: They're still convinced that they can make money off the house and ghosts that inhabit it. The promise of wealth can make people do strange things, including ignoring signs of clear danger. So they're remaining in the house in hopes that it can eventually make them a lot of dough.
Question: Otho says he was a paranormal researcher until "the bottom dropped out in '72." What does that mean - specifically, what happened in 1972?
Answer: In all probability, it has no relevance to the real world. In the world of the film, something unexplained happened in that year.
Question: Was Jane lying when she said that she decorated the Maitland home (she wanted Lydia to mention this to her parents)?
Answer: Jane appears to be taking credit for what Barbara and Adam had done. At the beginning of the movie, the Maitlands are discussing the home projects they've been working on. Adam has been refinishing cabinetry while Barbara has chosen wallpaper, and they're spending their two-week vacation working on the house.
Answer: It's never answered in the film if she actually decorated the house for Adam and Barbara, but there isn't really any reason to doubt it.
My interpretation was that Jane was always chasing a buck. She aggressively pestered Adam and Barbara to sell the house just to earn a commission. She was hustling the Deetzes for her decorating services. Regarding Barbara and Adam, they just didn't want anyone in their beloved house, much less having it redecorated after all the work they did on it.
But if she actually did, then I wonder if they would care as much about the Deetzes remodeling the home?
This is a stretch, but maybe Jane wanted to keep the house as close to how Adam and Barbara had it, like a shrine. It's not uncommon for those who lost loved ones to try and keep things as close to what was possible.
What I meant was, why would Adam and Barbara, not Jane, be so upset about the remodeling if Jane did the decorating anyway? Granted, they apparently chose to live with it.
That was probably a comfort thing. They learned they were going to spend over a century in that house, and it would be one thing if it was closer to what they were comfortable with, but the Deetzes' style was too much for them.
Question: Whenever Beetlejuice is shown in the model cemetery that Adam made, does it mean that a "real" Beetlejuice is the real cemetery in the town?
Answer: No. It's not meant to be an exact replica of the town cemetery. Beetlejuice just inserted himself into it.
Answer: They are very confused and probably not the sharpest tools in the shed. Juno probably told them they should do what she says and they immediately associated that with a coach.
