19 details you probably missed in 'Harry Potter and the Goblet of Fire'

The Warner Bros. logo shown at the start of the film is metallic, and Voldemort's snake, Nagini, can be seen slithering across the logo's reflective surface.

The zoom-in on the logo is the perfect setup for the opening scene, which shows Nagini slinking toward a tombstone.

This also serves as the primary introduction to Nagini, who becomes a pivotal character later in the series.

The film's director Mike Newell voices the radio announcer giving a weather update in the opening scene.

He also oddly gives the temperature prediction in Fahrenheit instead of Celsius even though Celsius is standard in the UK, where the film takes place.

Ron and Harry watch as Ceric puts his name into the Goblet of Fire.

Afterward, Ron waves and goes to say something to Cedric, but stops when the older student doesn't see him.

Ron looks disappointed for a moment. The slight of being ignored here may have added to his later anger when both Cedric and Harry were chosen as the Hogwarts champions.

After Harry's name is pulled from the Goblet of Fire, Alastor "Mad-Eye" Moody says that only an extremely powerful Confundus charm could've allowed Harry's name to be submitted when he's underage.

Igor immediately implies that Moody may have done this since Moody is the only one who seems to have an answer for how it could've happened.

Although Igor is indeed correct, this isn't confirmed until the very end of the film when Moody's true identity is revealed.

The Triwizard Tournament is an extremely dangerous event, as the ministry and Dumbledore mention throughout the movie.

During the first trial, there are boxes labeled "Hogwarts Field Supplies" visible in the champions' tent. But there's also a box underneath with a standard first-aid Red Cross logo on it.

We mainly see the ailments of Hogwarts students being treated by magical means throughout the series. But this seems to imply that the Wizarding World also replies on muggle medical equipment when necessary.

The Durmstrang students arrive at Hogwarts for the Triwizard Tournament on a ship.

The ship stays in the Great Lake throughout the school year and can be seen in the background of exterior shots of Hogwarts throughout the movie.

The front page of the Daily Prophet that Hermione gets in the Great Hall reads, "Ministry witch still missing."

Though it isn't referenced in this film, this is confirmed in the next movie to be a major sign that Voldemort is gaining support.

Ministry officials disappearing was one of the early signs of the First Wizarding War, the last time that Voldemort rose to power.

When a live band performs during the Yule Ball, they sing a song that mentions creatures viewers have seen in previous "Harry Potter" movies.

The lyrics include mentions of trolls, elves, unicorns, and hippogriffs.

Ron and Harry fought off a troll in the first film, house elves have been seen since the second film, unicorns have been seen since the first film, and hippogriffs were introduced in the third with Buckbeak.

At the end of the Yule Ball, Hermione and Ron got into a fight over her attending the dance with Durmstrang champion Viktor Krum.

After Harry and Ron leave, Hermione sits on the staircase in tears.

But she's not the only one crying there. A girl behind her is also crying and being comforted by two of her friends.

Myrtle speaks with Harry when he takes the egg into the prefect's bath, and she mentions that she saw Polyjuice Potion circling a drain.

This is a bit of foreshadowing as it's later revealed that Barty Crouch Jr. has been taking Polyjuice Potion to look like Moody.

Viewers know from the second film that Polyjuice Potion has a strong, disgusting taste and needs to be consumed frequently to maintain the appearance of the other person.

Moody always flinches when he drinks and can be seen drinking from his flask in almost every scene he's in.

When Moody interrupts a conversation between Harry and Barty Crouch Sr., Moody flicks his tongue over his lips.

Barty Crouch Sr. looks horrified and immediately leaves, but it isn't until later in the film that viewers understand why.

That tongue-flick tic was something his son, Barty Crouch Jr., did often — as shown during the Pensieve memory when Barty Crouch Jr. is revealed to be a Death Eater.

The seventh "Harry Potter" book and movie introduce the concept of the Deathly Hallows, a trio of magical items rumored to allow their owner to become the Master of Death.

The items are a true invisibility cloak, the Resurrection Stone, and the Elder Wand, symbolized as an overlapping triangle, circle, and line.

The symbol isn't officially revealed or explained until the later films. But when Dumbledore looks at his reflection in his office, the left side of the cabinet shows items arranged in a similar shape.

Before the third task of the Triwizard Tournament begins, the Beauxbaton students can be seen dancing and cheering in the stands.

Throughout the scene, they seem to be performing the "Macarena." The popular Spanish dance song came out in the 1990s, around when the film takes place.

Throughout the movie, the Hogwarts students cheer for Cedric much more than Harry in the Triwizard Tournament.

Before the start of the third task, the majority of the banners shown in the stands are yellow, the color of Hufflepuff, seemingly in support of Cedric.

When Krum, who's been bewitched, attacks Cedric in the maze, Cedric hits him with an Expelliarmus charm that causes him to drop his wand and end the fight.

Harry learned the Expelliarmus charm in his second year and uses it frequently throughout the series.

In later books, he's chastised for this, as Harry still prefers the defensive charm to ones that could harm his enemies to a greater degree.

Cedric's decision to use Expelliarmus, even when being attacked by someone, shows how alike he and Harry are. It indicates what his fighting style may have been like if he'd lived to see the upcoming war.

The three Unforgivable Curses are the Imperius Curse, the Cruciatus Curse, and the Killing Curse.

As mentioned by Moody during a Defense Against the Dark Arts lesson, Harry is the only known person who's ever survived the Killing Curse, which Voldemort used on him as a baby.

When Harry and Voldemort are dueling at the end of the fourth film, Voldemort uses the other two curses on him as well.

He uses the Imperius Curse to make Harry bow and get up and then tortures him with the Cruciatus Curse.

When Barty Crouch Jr., disguised as Moody, asks Harry what happened to him, he refers to Voldemort as the Dark Lord.

Harry doesn't notice anything is wrong until Barty asks about the others in the graveyard, and Harry realizes he never mentioned a graveyard.

Harry should've been suspicious a moment earlier, as Death Eaters are the only people who refer to him as the Dark Lord. Other wizards called him He Who Shall Not Be Named — or just Voldemort, if they're brave enough.

At the Hogwarts end-of-year banquet, Dumbledore usually presents the House Cup to whichever Hogwarts House won the most points during the school year.

The Great Hall is then magically decorated with the banners and colors of that house.

But in this film, the Great Hall is instead shown with black banners, indicating the school's mourning for Cedric.

The end credits have a fun little line about the dragons some fans may have missed.

The disclaimer reads, "No dragons were harmed in the making of this movie."
