So what would happen if a woman enacted the Santa Clause? Would she be subject a Gender Bender? Turn into Befana? Trigger the secondary "Must be married clause" from the second movie if she's a married woman and turn her husband into Santa?
In this troper's opinion, there'd be a balance between Gender Bender and Befana complimented (hopefully) by the Rule of Funny. A controversial idea, but a good writer could make it work.
Alternatively, some sort of magic ensures only men can enact the Santa Clause.
Just my thought, but she'd probably she'd turn into Mrs. Claus but get all of Santa's powers. To preserve the story, if a kid saw her she could just say "Santa's really busy this year so I'm helping out". She'd most likely be subject to some version of the Missus Clause, but whether the Santa powers would transfer to her husband upon marriage... hm. Likely the Powers That Be that Santa meets with in the second movie would rule on that. If Mrs. Clause had been doing a good job they'd probably declare she kept the powers, if she'd been just keeping her head above water until she got married they'd probably go ahead and give her new husband a shot.
"In putting on the suit and entering the sleigh, the wearer waives any and all rights to any previous identity, real or implied, and fully accepts the duty and responsibilities of Santa Claus, in perpetuity until such time the wearer becomes unable to do so, by either accident or design." That means, male or female, whoever puts on the suit becomes "Santa Claus." However, the "Mrs. Clause" specifically refers to "A woman of his choosing," which implies that "Santa" must be male. So either females don't fall subject to the Mrs. Clause, or females cannot be made subject to the Santa Clause in the first place, and only a male can put on the suit and become the new Santa.
Is anyone else horrified that that the third act of The Santa Clause 3 was essentially a race to murder a man and undress his corpse?
Not as horrified that The Wizard of Oz is about a woman killing another woman, framing the first person to pass by, and not letting said passer-by leave until she murders the dead woman's sister. Then, when the sister dies too, everybody dances around her corpse.
That "woman" was an evil witch who murdered and enslaved countless midgets, when she did not use her free time to live a double life in Kansas just to murder some orphan girl's dog. Oz was better off without her. Santa Claus, on the other hand, did not deserve his fate.
They weren't murdering anybody. The previous Santa had already fallen off the roof and slipped, that was his fate, it had been established as such for... what, fifteen years or so at that point, something like that? He was already dead. The time shenanigans basically are only a race to figure out who fits into that slot that caused him to slip and fall. Without the race, he still slips and falls because it had already happened.
What would happen if a kid or an animal enacted the Santa Clause?
Would the kid experience a epic growing up thing, and would Humanity Ensue for the animal?
If the Clause is a binding legal deal, then only an adult may enter into such a deal, unless the child had his parent's support and signed off as well. So no-go on animals, but it could depend on if the child was allowed to wear it by his/her parents.
Problem is, what a 'binding legal deal' is varies between jurisdiction and jurisdiction. In some, children can enter into contract. In others, the Clause very much is not a binding legal deal for Scott Calvin and others who became Santa in a roughly similar situation, as they were not informed of, and could not know of, the details of the contract beforehand.
It's not a binding legal contract, it's a binding magical contract. One that Scott agreed to, whether he read it or not, when he enacted the terms of it by putting on the suit. However, just because it's a magical contract and some of the rules are different from legal ones doesn't mean that all the rules are different. It may have some provision for people who would be incapable of fulfilling an adult role like Santa Clause... little kids, animals, people with severe mental problems, that sort of thing. Even if it doesn't, likely if a kid showed up back at the North Pole in the Santa suit, the elves would flip out and convene the council of Powers That Be to seek some sort of waiver.
If all Santas have to be married, what happened to the previous Mrs. Claus when Scott killed Santa in the first movie? Did she go back to her pre-Santa life? Did she die when he did?
Didn't they not discover the Mrs Clause until Scott's reign as Santa? Maybe no Santa has survived long enough for the Mrs Clause to factor into their contract.Which a completely different kind of Fridge Horror.
It may be that the only other Santas to survive long enough that the Mrs Clause would have kicked in were already married, lessening the Fridge Horror.
Scott was given eleven months to get his affairs in order. Mrs. Clause was presumably given the same amount of time.
If Jack wanted to be Santa, why didn't he just kill Scott?
It'd be a hell of a lot easier. Kill Santa, grab his coat before anybody else can. Don't have to worry about time-travel shenanigans.
Easier, yes. But challenging? No. Sometimes villains use unnecessarily complicated schemes because the obvious, simple solutions don't give as much of a challenge.
A better explanation would be that intentionally murdering Santa would be a lot harder than accidentally making him slip and fall off your roof by startling him.
Also you've got to figure that, bad as he was, Jack may simply not be a cold-blooded killer. (Pun not intended.) The other Santa was effectively already dead, all Jack had to do was replace Scott as the person who caused it, which probably to him is a little different than, say, stabbing someone in the eyesocket with an icicle. Plus, y'know... it's a family movie.
Jack is a magical being, so is Santa. There may be some kind of pact that such beings can't such go against other too directly without it going wrong.
The movie states that their powers don't work on each other. And I doubt the council of legendary beings would be so forgiving of him killing another legendary being, as opposed to having no idea about Jack Frost stealing the job.
What's the point of a nice list if Santa doesn't deliver presents anymore? In the third movie, after Frost becomes Santa, Scott makes his way to themepark!North Pole, where Curtis offers a pass for the nice list and reveals parents pay to get their kids on it. A bit later, Frost comments that he stopped delivering the gifts and just lets anyone that can afford it come up there. So, what's the nice list for?
Is anyone else disturbed by how emotionless the Elves are at the news of the old Santa's death? They don't show any grief and in fact aren't perturbed in the slightest. Didn't they have any affection for him at all? Who was this guy? Did he have a family like Scott? He at least would have had parents. Did the Elves notify them? Let them know they wouldn't have a body to bury? Did they attend the funeral?
Considering how old all the elves are, it's possible they're just used to it by now.
Why doesn't Scott just show everyone his magically growing beard to prove that he has no control over his new appearance?
