Wayne pulled down Griffin's swimming trunks, and he wasn't wearing anything underneath. This theory is plausible.
- H. G. Wells' book states that Griffin's clothes aren't invisible.
- He's be older than Mavis because he's the same Griffin; the serum made him immortal.
- As a side note, in the book, Griffin turned a piece of white cloth invisible, his sciency stuff just got destroyed before he could make invisible clothing. Since it's been about a hundred years now, he's probably had enough time to re-create his invisible-making machine. So he may be wearing invisible clothing most of the time, he'd be cold without it. So as for the swimsuit, it may be visible due to personal choice (he happens to like that particular pair and wants them to remain visible). As for the glasses, making them invisible might interfere with his eyesight somehow.
Jonathan has ADD/ADHD.
Have you SEEN the way he acts?
Jonathan probably had a girlfriend named Mina.
If there's a sequel (and if this weekend's opening numbers are any indication, there most likely will be), she will come looking for him and try hunting down Dracula and Mavis, making her the film's main antagonist. She'd probably be the girl that was "just a fling" that Jonathan mentions in the song at the end.
Possible plot synopsis' for a sequel are...
- Knowing that some humans are actually okay with the existence of monsters, Drac allows humans to come to the hotel as some sort of Visit Transylvania tour.
- A vampire/monster hunter would arrive as a guest, bent on taking down Dracula. Probably Van Helsing.
- Jonathan and Mavis return from their travels and announce that they are getting married.
- The monsters will need to meet Jonathan's parents and get accustomed to the world outside, a la Shrek 2.
- In a side story, Dr. Victor Frankenstein, now extremely old, has finally tracked down Frank and is determined to dismantle him for good.
- Horror villains from today's horror movies who are extremely scary, like creepy children, a girl crawling out of a well, dolls, chainsaw serial killers, or even Slenderman, battle with the classic monsters.
- A prequel explaing how the the five main monsters meet and how Dracula is related to Frankenstein.
- A prequel covering the actual construction of the hotel. Could also shed more light on Dracula's marriage and backstory.
- A prequel covering Jonathan's childhood.
- Jonathan brings his family to the hotel, not knowing that his family is an ancient order of monster hunters. Hilarity Ensues.
- Going to the ruins where Martha was burned. After all Jonathan did say he felt a spirit there.
- He is a Seventh Son, after all. Perhaps he was able to feel Martha's spirit there as a result.
- Humans and mosters will be living in harmony... for the most part.
Mavis may not share her dad's garlic allergy.
There's just something about the expression on her face when she asks "is that garlic" that makes her seem excited. Or perhaps she doesn't know she's allergic. Maybe she found out. She sounds upset when she's telling him about it later: "It was horrible! They had garlic on bread!" More likely the excitement on her face is really surprise, as she's probably never seen garlic bread before.
He briefly mentioned that he has six brothers, and that's a pretty big hint right there. He discovered the hotel, not out of curiosity and dumb luck, but because he was magically drawn to it.
He looks creepy, is possibly 600 years old, and wants to eat Jonathan.
- Alternatively, Quasimodo is a Legacy Character. He's not the real Hunchback of Notre Dame, but a ghoul who was named after him. He took the logical consequence of this by naming his pet Esmeralda. This seems to be supported by one of the knights saying "Quasimodo Wilson, you are coming with us." His last name's Wilson.
Probably something closer to, ironically, a gargoyle.
Most likely something to do with how during his life he still risked his life to protect another (he probably named his rat in memory of her) and was given a second chance. Unfortunately, since he's part gargoyle, he now has a taste for human.
Dracula's wife was human.
The backstory seems to suggest this. The mob killed her just for marrying a monster
, or they believed she was a vampire herself or probably a witch. Another reason why Dracula didn't want Jonathan around Mavis. That would make Mavis a dhampir (related to the theory above about not being allergic to garlic, since she might only have a few vampire weakness).
- On the other hand, her gift to Mavis includes a story about the meeting saying they were two bats who bumped into each other. While this doesn't fully rule out the possibility of this WMG, it does throw some serious doubt on it.
The Invisible Man's glasses are magic.
And I don't mean because they warp about to show his expression
. See, for the Invisible Man to be
invisible, light would have to pass through him completely - eyes included. But because light passes straight through his eyes, and therefore his retinas, he ought to be completely blind. At least without a pair of magic glasses allowing him to see. (Granted, the fact that he's able to kick Drac's ass while trolling him in the beginning without
them on puts a hole through this theory, but still.)
She will be human and Mavis will play matchmaker all the while saying "I told you so."
