A scene from the trailer for Captain Marvel.

There are a ton of unanswered questions about Captain Marvel, but one thing is very clear from the film's first official trailerwhich debuted on Good Morning America on Tuesday (Sept. 18): Brie Larson did not come to play.

The nearly two-minute sneak peek at the latest hero to hop off the Marvel train for a stand-alone feature focuses on the murky origin story of the half-human, half-alien superhero who appeared to get a call (a page, really) up to the big leagues from Nick Fury (Samuel L. Jackson) at the end of Avengers: Infinity War.

Jackson's Fury figures prominently in the intense trailer, providing the voice-over and setting up Larson's Marvel as a new kind of hero, as images of Cap blasting laser pulses from her hands while riding atop a train set her up as a mysterious force to be reckoned with. "I know a renegade soldier when I see one," Fury says. "It never occurred to me that one might come from above."

The first breakout female character from the Marvel Cinematic Universe -- Air Force pilot-turned-superhero Carol Danvers -- crashes to Earth in an alien ship, where she encounters Fury, as well as Agent Coulson (Clark Gregg) as she tries to square her vague Earth-bound childhood memories with the more sinister images in her head. In the wind-up to the coming Kree-Skrull war, we get a quick glimpse of Kree warrior Jude Law, as well as Danvers' Air Force pal Maria Rambeau (Lashana Lynch) and Ronan the Accuser (Lee Pace).

The movie was directed by Anna Boden and Ryan Fleck and takes place in the 1990s (you can tell because the trailer opens on a shot of a Blockbuster video store). Captain Marvel opens March 8, 2019.
