Charlie and the Chocolate Factory (film)/WMG

Everlasting Gobstoppers are made from Oompa-Loompas directly exposed to the chewing-gum-meal formula.
Note that, in this film, everlasting gobstoppers are kept in a liquid tank. The liquid is the same as that which was concentrated into the chewing gum, minus the blue dye. The gobstoppers are rolled around for the same reason Violet was -- to keep their shape.

If someone is allowed to keep consuming that formula for much longer than Violet did, then all the effects will become permanent. The "juice" will be metabolized and turned to solid flesh; once that happens, it can no longer be squeezed out. But there will still be juice building up for as long as that formula is consumed. The end result is a nigh-featureless being who will produce juice if compressed but will grow increasingly incompressible at their core as the flesh builds up.

When all of this happens to someone who was originally as small as an Oompa-Loompa, the result can pass for a large jawbreaker which can be sucked on indefinitely without getting any smaller.

If that kind of everlasting gobstopper ever enters distribution, then it will eventually do to its users what the gum did to Violet's body before she was squeezed. But, since they release the formula more slowly than the gum did, it should take longer before the point of no natural return gets crossed.

The tickets were not random -- but they didn't quite go as planned
If they had been random, then Mike Teevee would not have been able to use his leet hacking skills to intercept one. Because the wrong person -- one who hated chocolate -- got the fourth one, Wonka delayed sending out the fifth one (the one Charlie ultimately got) while he thought out an appropriate trap for Mike; by the time he had, the contest was nearly over, and Wonka had to change the fifth one's target to "someone who lives close to the factory."
 * ...so basically, Wonka planned everything that happened to the kids in the factory before they even arrived?
 * Didn't we already know that?

Grandma Georgina is psychic

 * When is the one time she 'knew exactly what she was talking about'? When she happily proclaims that 'things are going to get much better.'

Charlie got the Golden Ticket because he really did want it more, and never gave up hope.
If he hadn't been there to hear that the original fifth ticket-finder was a fraud, then it wouldn't have been in there when he opened it.

Wonka is, or thinks he is, Zordon.
He believes that he is Zordon revived by some force, and may be right.

Since he made some poor choices back in his era, he's approaching things differently. He has none of Zordon's magic items, but knows how to make some crazy ass candy, so he decides to create his Rangers a different way. For example, the Factory is the new Command Centre, with the business giving him a way to set things up. He's having trouble building the Zords so he's instead trying to create alternative means for the Rangers to combat giant monsters, such as the Shrink Ray. The Oompa-Loompa's are actually a massive group of Alpha's ranging from 7 to over a hundred, each with a faulty version of Alpha's friendly personality, resulting in the musical numbers. The kids are obviously intended to be his Rangers, and he's trying out giving them new abilities. His fondness for his Rangers makes his anger at their disobedience into what appears to be Wonka's submissive attitude to the children's fates. He just keeps thinking they're going to do the right thing. Then they don't.

Veruca: Wonka tries to give his new Pink Ranger control over animals, starting with Squirrels, but she's too impulsive and ends up with his failed Repellent Pheramone experiment. Augustus: The Yellow Ranger (because even though he wears Red, he isn't really leader material) is given shapeshifting abilities after being turned to chocolate. Or at least becomes covered in it, which impedes the progress somewhat. Mike: The Black Ranger was going to get size changing powers after helping Wonka reverse the Shrink Ray, after which he'd help work on the Zords. Violet: The gum was a failed attempt to make a giant Ranger, but it worked excellently in giving his new Blue Ranger super human reflexes. Her chipper attitude once she's drained suggests that if approached again, she may accept the role of Ranger. Charlie: The Red Ranger. Charlie was supposed to be granted flight by the Fizzy Lifting Drinks, but the other potential Rangers accidents derail the tour and he never gets to that room.

However, there is hope with Charlie not getting incapacitated and Violet's attitude.

Grandpa Joe is a massive Papa Wolf in this film.
If we believe the theory that the Depp film is a 'sequel' to the Wilder version, then Grandpa Joe is one of the few people who believes the tales of the previous naughty children. He might even know.

He knows that Charlie could become a victim of Wonka's twisted plan. He manages to regain his mobility so that Charlie can experience his dream but still be protected.

The Oompa-Loompa's only improvised a few lines.
They only planned the songs for what would tempt the children, not for what flaws the children happened to have, thats why it doesn't match up all the time. The song to Augustus was a song for a glutton, at a place the Oompa-Loompa's knew someone would be greedy enough to try to take the chocolate from the rive and what would happen if they fall in, the song to Violet wasn't about competition but about chewing gum, which was all the Oompa-Loompa's probably would know about someone who greedily takes the gum, the song to Veruca was more about garbage (which the Oompa-Loompa's would presumably know that someone who tries to take a Squirrel would be considered bad and thrown down into the garbage chute) and less about being a spoiled brat, and you only got more of the spoiler brat parts towards the end, presumably after the Oompa-Loompa's had time to improvise it, and finally, Mike's song is mostly about television and not his character flaw, because the Oompa-Loompa's could only make assumptions that someone tempted by the room likes television.
 * It follows that either they had songs prepared for several other rooms in the factory, or Wonka arranged the specific tour route beforehand and let the Oompa Loompas know far enough in advance to prepare the songs.

Charlie's father will soon be hired by NASA for an absurdly high salary.
Those toothpaste tubes filled with astronaut food can't screw the caps on themselves, can they?

Veruca grows up to be the Batman villianess The Absence
Hence her head sounding empty when the squirrels tap on it.

Wonka is a Time Lord.
Someone had to say it! He just built a regular-sized factory as a cover: the front door is really the door to his TARDIS. It's bigger on the inside, and he distracts his guests with songs and dances so they don't notice when they're traveling through the time vortex. Then, when they're good and distracted, he leads them out through another door (the TARDIS's door again) into an alien planet. Oompa Loompas are aliens. And all the chocolate trees are the planet's natural flora and fauna!

Wonka Only Hates Mr. Salt.
At the beginning of the film, Wonka didn't really like anybody due to his own misanthropy, but he took an immediate, strong dislike to Mr. Salt for seemingly no reason at all. The rotten kids all got in trouble because they didn't listen to Wonka's warnings, but Salt was set up. Wonka wouldn't let him go after Veruca until she'd already gone down the garbage shoot, and counted on the squirrels to knock Salt down after her if he didn't fall. Wonka hated Mr. Salt because, as a tall, posh grey-haired Englishman, he reminded Wonka of his father.

Now try watching the movie again and tell me you don't see it.
