Rey, Finn, BB-8 and Poe Dameron have been on an epic journey since 2015's Star Wars: The Force Awakens. And one year from now, their adventure is going to meet some kind of conclusion when Star Wars Episode IX comes to theaters.

The movie has a lot to live up to. Abrams will need to find a way to offer an ending to the revived Star Wars movie universe following a mixed reception to The Last Jedi and Solo's box office flop. Also, it's not like his Force Awakens was criticism-free -- some fans knocked it for evoking the original Star Wars film too predictably. Not to mention, he'll need to find a graceful way to allow for Leia Organa's exit following the death of actress Carrie Fisher in 2016.

But with production underway, there is plenty of time before Star Wars returns to movie theaters. Here's everything we know about the film so far.

Star Wars Episode IX: (Insert eventual subtitle here) will hit theaters around the world on Dec. 20, 2019.

J.J. Abrams is directing. Originally, Colin Trevorrow was tapped to helm the movie, but he parted ways with Lucasfilm in September 2017 over creative differences. However, unlike the director change that befell Solo, where Ron Howard took over the project after original directors Phil Lord and Christopher Miller were in production for six months, Abrams began work on the project during preproduction.

We're expecting a good mix of the new faces seen in The Force Awakens and The Last Jedi to make their return in the 2019 movie. The official cast includes:

The official cast announcement on July 27 came just before the start of filming, confirming that Mark Hamill and Billy Dee Williams are back. It also noted that Fisher's Leia will return through the use of unseen footage from 2015's The Force Awakens. Episode IX was originally supposed to heavily feature Fisher, Lucasfilm President Kathleen Kennedy confirmed to Vanity Fair, but Fisher died in December 2016. The studio further confirmed that it wouldn't digitally re-create her like it did for 2016's Rogue One.

"Finding a truly satisfying conclusion to the Skywalker saga without her eluded us. We were never going to recast, or use a CG character. With the support and blessing from her daughter, Billie, we have found a way to honor Carrie's legacy and role as Leia in Episode IX by using unseen footage we shot together in Episode VII," J.J. Abrams said in the July casting announcement.

Naomi Ackie, Richard E. Grant, Keri Russell, Dominic Monaghan and Matt Smith also join the Star Wars galaxy in yet to be named roles.

Composer John Williams will also score the movie, as he has with every numbered entry in the Star Wars saga.

And while it's not impossible for Harrison Ford to potentially return as Han Solo, there are no official announcements quite yet.

Unseen footage from The Force Awakens will be used to bring Carrie Fisher's Leia into Episode 9's story.

This early we can only speculate, so let's go over what we know about a few characters' whereabouts and how things could move forward. 

Rey: After turning down Kylo Ren's offer to let both the First Order and the Resistance perish and instead conquer the galaxy together, Rey is last seen on the Millennium Falcon with the sacred Jedi texts taken from Ach-To. It's likely she will continue her own version of Jedi training using a combination of the texts, personal practice and maybe some off-screen mentorship from Leia Organa. Also, she JUST MET Poe Dameron, so it's time to see what her dynamic with the fly boy might be. One other thing: Will J.J. Abrams choose to flesh out the story of her parentage, or will he keep her as an orphan that was sold off by her parents for drinking money?

Finn: Finn is now possibly dating Rose and reunited with his bestie Rey, and Finn and Rey are expected to stay paired up for Episode IX. While he's fresh off defeating Captain Phasma during The Last Jedi, there's still plenty of room to flash back to Finn's Stormtrooper history should it be relevant to the new movie.

Kylo Ren: The new supreme leader of the First Order could be looking over his shoulder, making sure no one has any evidence he's the one who killed off Snoke. That said, after having his connection to Rey cut off by the end of The Last Jedi, Kylo might now be fully embracing his role as a Sith leader.

Leia: After her gorgeous and surprising ability to fly through space using the Force left her in a coma, Leia woke up to finish off the movie, but her condition is otherwise unknown. Due to the Fisher's death, we can expect either a time jump that would sadly reference the off-screen passing of her character, or some other plot point that would separate her from the other Star Wars characters. There may be a book or some other piece of extended material filling in whatever gap Episode IX can't without having the actress. Editor's note: The studio announced July 27 that it'll use unreleased footage of Fisher from The Force Awakens in Episode 9.

There are a lot of rumors on the internet already about Episode IX, including the possibility of some surprise appearances:

As more rumors pop up, we'll add them to this list.

We don't yet know what the deal is with *that* character who appears in Solo. I'd speculate he'll appear in some Star Wars movie, but likely not Episode IX. We can tell you all about the character's appearance in Solo, though, and all about that character's history (along with why it's doubtful Episode IX will be what pays that cameo off).

There's a lot on the way as long as you're willing to expand beyond the movies.

First is Star Wars Resistance, an animated series coming to the Disney Channel this fall that takes place just before The Force Awakens. The show comes from creator Dave Filoni, who just wrapped the Star Wars Rebels series and also led Star Wars: The Clone Wars. While Resistance will showcase new characters, it will also feature Poe Dameron and Captain Phasma as voiced by Oscar Isaac and Gwendoline Christie, respectively.

The Clone Wars, originally cancelled in 2013, is also getting revived with a new 12-episode season coming to Disney's upcoming streaming service sometime after its 2019 launch.

A live-action Star Wars TV series by Jon Favreau is in the works, also heading for Disney's upcoming streaming service. But details about that specific Star Wars series aren't yet available.

And if all you care about are Star Wars movies, you can also look forward to TWO trilogies. The Last Jedi director Rian Johnson will create one, and the other is from Game of Thrones creators David Benioff and D.B. Weiss.
