Let us know which holiday hit is your favorite in the comments.

The NCU is a magical, romantic holiday world where most of the men are royal bachelors and most of the women are Vanessa Hudgens.

If you're a heroine working for the holidays, a spontaneous carol singer, or a potentially magical old person, you might just be in the NCU.

There are ten total films in the NCU.

In order of release, they are "A Christmas Prince,"

"Christmas Inheritance,"

"The Holiday Calendar,"

"The Princess Switch,"

"A Christmas Prince: The Royal Wedding,"

"Holiday in the Wild,"

"The Knight Before Christmas,"

"A Christmas Prince: The Royal Baby,"

"Operation Christmas Drop,"

and "The Princess Switch: Switched Again."

The NCU began with 2017's "A Christmas Prince."

This movie established the story basis for each of these films.

- Come with me, please.

An everyday heroine enters a magical Christmas world where she finds love and herself.

Beyond this, "A Christmas Prince" and its two sequels undoubtedly form the main pillar of the cinematic universe.

Think of Amber as Iron Man and if Amber is Iron Man, then Vanessa Hudgens is Captain America and the Hulk and Thor.

- Do I really need to explain?

While "The Princess Switch" and "The Princess Switch: Switched Again" obviously form the second royal pillar of the NCU,

"The Knight Before Christmas" also ties in more subtly.

- Your great grandmother's cousin Cecil fled the country after a dalliance with a vulgar American divorcee.

It was rumored that Cecil settled in the United States.

And if Cecil has one descendant in America, why not two?

This explains how Brooke fits into this world.

She's another holiday-loving Hudgens destined for royal romance.

These films have similarly enchanting royal stories but "A Christmas Prince" and "The Princess Switch" are also connected in deeper and more meaningful ways.

- We feel a review is prudent.

Aldovia, Belgravia, and Montenaro are the three fictional countries prominently featured in these two film series.

In "A Christmas Prince: The Royal Baby," this map even confirms that Aldovia and Belgravia are neighbors.

Of course, the first link between these two worlds came in "The Princess Switch," when Kevin and Margaret watched "A Christmas Prince" on Netflix.

- Your favorite?

- No, it's your favorite.

- Right.

Then, in the sequel, Amber and Edward are actually present at Lady Margaret's coronation.

This suggests that within the NCU, these movies could be biopics or even documentaries, rather than fictional films.

It follows that the televised appearance of the other movies,

including "The Holiday Calendar," "Christmas Inheritance," and "Holiday in the Wild," would be documentaries or biopics as well.

- There is nothing like a happy ending to make someone cry.

The biopic slash documentary angle makes sense, as each of these ten films is focused on a particularly newsworthy story.

Just like a royal wedding, the transformation of a party heiress or the saving of an elephant orphanage are real events that are likely famous enough within the NCU to be made into films.

Even "Operation Christmas Drop," which has yet to appear on Vanessa Hudgens' TV, establishes just how newsworthy the story is within the movie.

But you're probably still wondering, "How exactly did this universe get started?"

Well, all of the films in the NCU are made by MPCA in partnership with Netflix and produced by Brad Krevoy.

It all began when they needed a film to have on TV in 2018's "The Holiday Calendar."

The creators decided to intentionally link the films in deeper and more complex ways, planting Easter eggs, or acorns, in their other collaborations with Netflix, too.

- What with the Belgravians here in Aldovia as well. It seems royals marrying outside of the noble classes has become quite fashionable.

And that's everything you need to know about the Netflix Christmas universe.

Thanks for watching and happy holidays.
