"The past is not what it seems." The three biggest clues from the Frozen 2 trailer.

From the moment Disney released Frozen, people were calling for a sequel.

The children (okay, and us), wanted to see more of sisters Elsa and Anna, and yes we absolutely needed another Olaf solo. It would also be nice to have a little variety, ya know, after having to watch Frozen on repeat, over and over and over again.

More than five years on, we’re finally learning more about what will happen to our kids favourite Disney characters in Frozen 2, after the release of the trailer for the upcoming movie.

In February we were treated to a ‘sneak peek’ trailer, which showed us Frozen 2 was going to be a little darker in tone and the latest trailer has stuck with that, but also gave us a glimpse at the epic adventure the characters – yep, Kristoff, Olaf and Sven are there too – will go on.

See for yourself in the Frozen 2 official trailer. Post continues below video.

It’s also clear Disney has spared no expense, because the level of detail and landscapes are beautiful.

While we could ramble on about how great the whole thing is, we thought we'd break down the trailer into three key takeaways that you may or may not want to share with the little people in your life.

1. We'll learn about how Elsa got her powers.

One of the cute little trolls who we met in the first film is seen in the trailer telling Elsa "the past is not what it seems", which is uh, ambiguous, but he sets her and the clan off on a mission north in order to discover the truth.

The trailer very heavily implies the mystery is related to Elsa's powers - why and how she acquired them, or how they fit in to a wider 'magical' world.

Pabbie the troll tells Elsa they always worried that her powers were "too much for this world", but now they hoped "they are enough", so we should also learn the true extent (and limitations) of Elsa's magic.

This all points in the direction of Elsa needing to save the world. No pressure.

2. We will find out more about Elsa and Anna's parents.

In the first film, basically all we knew about the King and Queen of Arendelle was that they struggled with what to do about their daughter's powers before drowning at sea during a storm.

It was... not great for them.

Last year songwriters Kristen Anderson-Lopez and Robert Lopez told Variety that in Frozen 2 "we know the parents a lot better," indicating they play an important role in the sequel. No word yet if that's all going to happen in flashbacks, or if the weird conspiracy theory that they didn't actually die, and instead washed up on an island and became parents to Tarzan (no, really) is legit.

The larger role of Anna and Elsa's mum and dad in the sequel is hinted at in the trailer: Obviously, "the past is not what it seems" could also refer to the parents and there's a very brief flashback of their mother looking at the Northern Lights.

This also ties into the mystery of Elsa's powers - could they be genetic?

3. Elsa has a patronus.

Is this the Harry Potter/Frozen crossover we absolutely do not need?

Thankfully no, but a patronus-like horse pops up multiple times in the trailer.

No one:

JK Rowling: "Elsa's Patronus has been a water horse who has been patiently waiting in the ocean for over 30 years to show her the way to find herself"

It introduces what appears to be a new (magical) character, Nokk, a horse spirit that manifests through water.

The new Frozen 2 synopsis states that "Elsa encounters a Nokk - a mythical water spirit that takes the form of a horse - who uses the power of the ocean to guard the secrets of the forest".

In the first half of the trailer, Nokk appears when Elsa plunges into the ocean when attempting to cross. At first, Nokk appears just a bit... inquisitive, before saving Elsa.

Later Nokk returns. It seems like it is acting as a guide, creating visions of what Elsa will face during her travels - like giants.

According to Screenrant, Nokk originates in Germanic legends, acting like a siren that lures men to their deaths rather than saving them as we see in the trailer.

Overall, the trailer seems to raise more questions than answers. It's also missing any musical numbers, which means that you'll have to put up with Let It Go for another six months before a new Frozen song takes over your life.

Frozen 2 will be released in Australian cinemas on November 28, 2019.
