In the Harry Potter universe, apparating is only loud whenever you're bad at it. Dumbledore apparates almost silently. Bellatrix apparates with a slight pop. Dobby and Creature (house elves) apparate with a loud crack. It seems as though the better the wizard, the quieter you apparate. -u/boomshiki

The real reason Batman is strong enough to compete with literal gods (IE Superman) is because of one of his greatest fan's. A comic book hero named Bat-Mite is a Dark Knight superfan and will do anything to protect him. The theory is that Bat-Mite is actually the powerful one. So powerful in fact that he warps reality to give Batman a fighting chance. Basically a kid changing the rules mid-game. -u/CasuallyCritical

In 'Always Sunny...' Charlie claims to have studied Bird Law. One theory claims that he was taught this by his Uncle Jack. Uncle Jack was trying to teach him Parody Law, but Charlie heard it as "Parrot-y" law, which his mind translated to Bird Law. -u/cheese2194

In the Tim Burton classic 'Edward Scissorhands', the titular character never runs. He either walks or shuffles. The theory states that Burton, knowing kids would try to imitate the character, didn't want him running, because kids aren't supposed to run with scissors. -u/SmokeAndGnomes

The Avatar universe is following the Chinese philosophy of Wuxing. The five phases of Wuxing are Wood, Water, Fire, Metal, and Earth. The theory claims that the first film was wood, two was obviously water, three is set to be about fire. While future movies may be up in the air, there are five planned in total. - u/Impacatus

In 'The Fast and the Furious', when Dom goes to prison as a youth, he is secretly chosen for human enhancement trials which later come back in 'Hobbs and Shaw.' This explains why his muscles regenerate and he's basically immortal/superhuman throughout the films. -u/savagezelda

Goofy actually DOES know Powerline in 'A Goofy Movie.' Long story short, Goofy might be more famous than the movie lets on. Mickey Mouse is a small character in the film, but judging by the fact that someone has a Mickey Mouse phone, it's safe to assume Mickey is famous in this world. So when Mickey waves to Goofy on their road trip, it begs the question how many famous figures does Goofy know? That theory is confirmed by Powerline not kicking them off the stage at the end. -u/MNM0412

A detail in 'The Batman' proves that Falcone knows Bruce Wayne is Batman, and takes it to the grave. Falcone shares a story of Bruce looking down on him as he's getting surgery, and that Falcone 'remembers his face.' Fast forward to Batman looking down on Falcone. He finally connects the dots. -u/xviandy

Grandpa Joe is a degenerate gambler. He puts all of his confidence in Charlie to win a golden ticket, based on nothing. They don't have money to by loads and loads of chocolate bars giving Charlie a higher chance of winning. Instead he uses the last of the family's money on two bars, getting Charlie's hopes up. It's pure luck that Charlie wins a golden ticket. Gambler mentality right there. u/Cheeseanonioncrisps

The Hallmark universe is a dystopian world where Santa rules all. Many families are wealthy and happy, as Santa rewards all of the "nice" citizens. Most of the movies include some tragic death story, or lack of parents. This is because they were "naughty" citizens at one point. The punishment in Santa's world is death. -u/ExistingCoyote2

In 'Home Alone' it's not Kevin's dad who makes all the money, but his mother. This theory claims that Catherine O'Hara's character is the bread-winner because she works in fashion. She dresses very well for the time period, always has expensive jewelry, and always carries a large amount of cash. It makes sense given the sewing machines and mannequins in the house. She's the one who can afford to take these lavish vacations for the whole family. -u/IBuiltABanana

In Disney's 'Hercules', there is a throwaway joke about the Titans going the wrong way. Hades ends up 'correcting' them saying "Mt. Olympus is that way." In reality it's not that the Titans were stupid, they were just heading to Mt. Othrys, their ancestral home. Which is where they assumed Zeus would be. -u/EquivalentInflation

Why did the Joker show up and - seemingly in the same breath - leave the party so quickly/easily in 'The Dark Knight'? The theory is simple. He got the answer he needed. The Joker goes to the fundraiser party to test his hypothesis that Harvey Dent is Batman. Harvey isn't anywhere to be seen. Then he threatens Rachel, Harvey's girlfriend, and suddenly Batman appears. Batman then risks his life to save Harvey's girlfriend. That's all the Joker needed to know. -u/atlhawk8357

Imhotep isn't actually the bad guy in 'The Mummy.' Unfortunately he's just bound by the rules of the Magi curse. He is mummified in the most barbaric of ways by the magi. They even feared doing this ritual. If Imhotep is resurrected then he must restore his body by who discovers the book of the dead. There is a warning Imhotep will kill who opens the chest with the book. So he kills the people who opened the chest to resurrect his body. If only the main characters worked WITH Imhotep, many lives would've been spared. -u/Kroosh333

When James Bond orders a "Vodka Martini, shaken not stirred" it's a clue to the bartender of who he is. Intelligence has already made the bar/lounge aware that a person who orders this drink should not be given alcohol. Bond has to stay sharp on the job, so when he orders the drink, the bartender already knows it means no alcohol. -u/Albatraous

The Joker is actually a crooked and/or former cop in Gotham. It explains his obsession with catching Batman. He knows the mob, crooks, underground criminals just as well as any cop would. He also has access to weapons that he could've taken from lockup. His insanity was triggered by the fear toxin in 'Batman Begins', maybe he even gave himself the facial scars. -u/Remote_Impact_3927

When characters in 'SpongeBob SquarePants' scream "Tartar sauce", they mean "Hell." Tartar sauce sounds a lot like 'tartarus,' one of the Greek forms of Hell. And what do you put tartar sauce on? Fried fish. -u/calvinocious

All of the dinosaurs are sick in 'Jurassic Park.' This is backed up by the fact that neither the raptors nor the t-rex could smell their prey in the kitchen scene, and the rain scene with Alan respectively. It seems as though the moisture created by the raptor's breath on an inside window is another clear sign that the creatures are sick. -u/astro_not_yet

What seems to be another throwaway joke, actually makes sense as a response on Star-Lord's part. In 'Avengers: Infinity War', Tony Stark says "You're from Earth?" to which Star-Lord replies, "No, I'm from Missouri." Throughout the galaxy Earth is known as Terra. So he's technically not wrong. He's from Missouri, Terra. -u/Soyoulikedonutseh

After they get the ball back from the Beast in 'The Sandlot', it's safe to say Mr. Mertle would love to watch the boys play ball. Unfortunately he's blind. Since Smalls was never that great of a player anyway, he begins calling the games, play-by-play style to Mr. Mertle. Combine that with Mertle's baseball trivia, facts, and stats. It makes total sense that Scotty Smalls would go on to call games for the Dodgers. -u/two2teps
