Update: The Captain Marvel trailer is here!

Captain Marvel's trailer will finally release tomorrow - Tuesday, September 18 - but when exactly will you get the first look at Brie Larson's Carol Danvers in action? Marvel fans have been anticipating Captain Marvel since the film was announced in 2014, and eagerly anticipating a teaser trailer since Nick Fury paged Carol desperately in Avengers: Infinity War's post-credits scene.

The first female-led superhero movie in the Marvel Cinematic Universe, Captain Marvel will follow Larson's Danvers as the half-human half-Kree member of the intergalactic Starforce, before she's brought back to Earth to tackle a Skrull invasion, meeting Fury and Agent Coulson along the way. So far, Marvel has been incredibly tight-lipped on the movie, talking about the hero in broad terms and only providing an official first-look at Larson in costume two weeks ago in an EW cover story.

That all changes tomorrow. Brie Larson is set to appear on Good Morning America on September 18 to promote Captain Marvel, and all signs point to the star bringing a trailer with her. We don't know when in the show, which airs from 7am to 9am EST, although based on Marvel's prior form, we can expect it to drop near the end: the Captain Marvel trailer will likely release between 5:30-6am PST/8:30-9am EST/1:30-2pm BST. It's possible it will be a little earlier, but a later slot in the show is definitely more likely.

It's worth noting that this will be a teaser trailer for Captain Marvel, and while Marvel's teases tend to include more footage than others, this will still be on the lighter side; it'll be likely building up to a proper reveal of Carol rather than full of Marvel cosmic spectacle (the film is still six months away, so complex visual effects won't be finished).

So, with that in mind, what can we expect? Seeing Captain Marvel, powers on full show, is a guarantee. Also a safe bet given their prominence in the EW photos are a younger Nick Fury (Samuel L. Jackson) and Skrull leader Talos (Ben Mendelsohn), with possible teases of returning Guardians of the Galaxy characters Ronan (Lee Pace) and Korath (Djimon Hounsou). A bigger question is how much we'll see of Jude Law: originally said to be played by Mar-Vell, he's since been coy and signs now point towards him being someone else entirely. With that in mind, details on Law may be light.

While audiences have been waiting a long time to see Captain Marvel in action, this time next year that will have changed completely. As well as her solo movie in March, she will be a central member of the Earth's Mightiest Heroes' attempt to undo Thanos' snap in Avengers 4. It all begins tomorrow with the trailer!
