Wild Mass Guessing for The Breakfast Club.
Bender grows up to become The JokerBoth seem to enjoy pushing people over the edge. Both are outsiders. Both carry a hatred for authority figures. Bender's father beats him, and one of the Joker's stories for his scars involve an alcoholic father. The Breakfast Club is set in Sherman Illinois, which is not too far from Chicago, which is what the The Dark Knight Saga's Gotham is supposedly based on. Perhaps after graduation, Bender suffers some sort of traumatic accident that leaves him scarred physically and drives him to insanity. With that in mind...
Brian grows up to be Mike Engel.The news host of Gotham Tonight was portrayed by the same actor. Perhaps Brian wanted a cooler name. And while we're at it...
Allison grows up to become Catwoman.She does enjoy stealing things.
Bender does this regularly.Its clearly established that Bender is constantly in detention. Maybe he secretly likes bringing kids of different cliques together, if only for one day, as part of an experiment of sorts on society. Maybe he has it methodically planned out: observe them, comment about their parents, take them to his locker to get his pot, and get them high so they eventually spill their secrets and grow closer. Maybe thats where he met all the girls in his wallet.
Brian wanted to get stuck writing the letter.When Vernon came down on them for skipping the assignment, Brian would get off scot-free. If Vernon tried to get him into trouble again, the report in his handwriting would clear him and probably put some suspicion on Vernon of his corruption; the other teachers would start watching Vernon a lot more closely. Meanwhile, the other four would think that he had been "sticking it to the man" along with them instead of doing the assignment like the sycophant they thought he was.
There were only four students; Bender was the "unrestrained" persona of Brian.The students didn't call him on his differing stories because of the things "Bender" had already made up. Two clashing stories don't seem like much when there are three other stories he insists are true. The charge wasn't just a flare gun in his locker, but a flare gun set up to blow up in front of anyone who tried to get into his locker without disarmng it, which happened when a teacher noticed that his elephant lamp looked suspiciously like a water hookah when the lamp mechanism was taken out. Bender's locker was an empty pair of lockers on the other side of the school that he set up to avoid 1) being caught with a bag of weed in his locker, and 2) burning it all up when the trap was triggered. Which and how much of their backstories were true is unknown. Odds are, he ran away a few months or couple of years ago and has lived in an abandoned house ever since. Any scenes where Bender insults Brian, such as the lunchroom scene, are just him mumbling and being surly and (to anyone listening) mocking the reaction of someone who might object to his insults. At the end of the film, Claire falls for Bender and Brian, since they're the same bad boy to her. The Brian persona writes his idea of a subversive note in which the "extra" character seemed like something he threw in for contrast against the popular athlete and "cool" criminal (like how the basket case contrasted against the princess).
They all killed themselves. Well, not Claire...Detention is purgatory, place where the kids repent for their sins. The nerdy kid DID top himself, as did the Jock because he felt so ashamed for what he'd done. Claire went to the mall with her friends, the car crashed and she died. Allison had nothing better to do bt kill herself and Judd Nelson is Judd Nelson, so he killed himself too.
Anything from the pot smoking on was a hallucinationIt was REALLY good pot. Explains the lack of logic in the last five minutes.
Alison is a virginJust before she blurts out that she is a nymphomaniac, they are discussing virginity. She has been watching them silently all this time, maybe she thinks that stating their virginity is some kind of 'bonding' exercise or a 'right of passage' to become friends, so she lies after seeing people teasing others about being virgins.
Bender was a cartoon character.As Judge Doom said, "No toon, can resist the old Shave-and-a-hair-cut!" When Bender is hiding under her table, Claire hits the first five notes on the desktop, to which Bender replies with the two-bits! follow up hits.
They're all dead.The characters exist in the DC Comics universe. They have died, and the entire movie is them gradually passing over and coming to terms with their own deaths. Alternatively, they were all alive and actually in detention, up until the janitor arrived, went nuts and killed the kids (he obviously hates them). Allison is in fact Death of the Endless, acting in her role as a psychopomp.
They're all dead and being judged by the statue.It's watching over them, deciding... deciding....
Breeding pairs?The kids and the few adults seen are the last few humans left. This detention scenario is brainwashed into them by caring aliens so they will breed.
The kids don't socialize with each other on Monday......at least not in school. They know that their respective cliques would tear them apart, so they pretend everything's the same to avoid conflict. But after school every day, they hang out with each other and away from their other friends.
Rather than becoming a bum, John Bender........ eventually writes a successful screenplay based on the events of the Saturday, in which his own counterpart is named "John Hughes"!
Bender did punch VernonThe second half of the film was his hallucination to cope with going to prison after punching out Vernon.
Claire slept with all the men in the group.It is heavily implied during the scene where Bender rips up the books, that Claire may have slept with Andrew at one point. It was also heavily implied by Bender (whom also guessed correctly that Andrew hated his parents.) that he slipped her the "Hot beef injection." She ended up with Bender in the end. Plus she did convince Brian to write the essay for them all, so he must have had something out of it.
Allison slept with Brian and Bender.Bender claims to have seen her before. How else would she get close to Brian and steal his wallet.
Allison killed her parents.Makes sense, she stole Benders knife and never gave it back, unlike Brian's wallet. Her parents ignore her so they wouldn't see it coming.
Brian's parents have connections with the faculty.How else would he get Saturday detention for bringing a flare gun to school?
Brian's parents are pushing him to be perfect for selfish purposes.It's appropriately cynical, and fits in with his mother's overall sleazy mien. Brian's mother and father don't see him as a human being, but as a means of earning prestige in Shermer. They grossly insert themselves into his academic process, and they surely take the credit for his successes. Furthermore, the higher the GPA, the more money you make. Think about that for a second.
Vernon goes to jail.Brian secretly placed recording devices into the library and storage closet. Vernon's threat to Bender has been recorded. Why else would John smirk at Bender when he asked if he was threatening him. He knew about the devices and was just confirming it. The threat is placed all over the announcements on Monday. Vernon gets fired and arrested.
Allison does end up running away.She goes to New York, where she eventually changes her name to Marla Singer.
This becomes a regular thing.All the kids find excuses to rejoin Bender every Saturday that he has detention.
Allison has Asperger's Syndrome .I am an Aspie (I was diagnosed by professionals), and Allison is my favorite character. I see a lot of myself in her, especially her reason for being in detention she had nothing better to do.
Allison is the sister of Cameron Frye.Or possibly half sister. We never see Cameron or Allison's family, and Cameron's dad doesn't seem like the most loyal man, so he could've knocked another woman up, or Cameron's mom had her with another man. Both are weird and don't seem to be the most popular in school. Their home lives are both unsatisfactory, and the way Ferris describes Cameron's house (Like a museum, you can't touch anything and it's cold) was a deleted line from The Breakfast Club describing Allison's house.
Brian is a closet homosexual.The only guy who isn't romantically interested in girls and he whistled at Andrew when he took his shirt off.
Making a remake of this movie set in the present decade would be all but impossible.We know the students managed to bring stuff into the library that Vernon would probably have blown a gasket if he knew. If five teenagers today were consigned to detention and left unsupervised, they'd all pull out the smartphones they'd smuggled in, soon as they were left on their own, and would spend the day calling their friends or messing around online, never saying a single word to one another.
The parents we see in the film are strawmen.A theme of the film is how the members of the Breakfast Club recognize the hollowness of their respective familial/social circles and become determined to make good rather than succumb to the faults of their parents and peers. In the opening of the film, we briefly see Claire's father, Brian's mother, and Andrew's dad. These three characters may seem like one-dimensional Jerkasses, but it is very likely that this was intentional, as they are meant to be jabs at the failings of some suburban parents. For instance...
Allison is not in detention because "she had nothing better to do".She said herself that she's a compulsive liar, she lied about a bunch of other stuff. When she gave her reason, it seemed to be mostly a joke played for laughs. Even if she wanted to get away from her parents, it feels like literally any other place would be more fun than detention. As for what she actually would've done to get detention is completely up for debate, personally I'd guess she got caught stealing something.
