Brie Larson’s cosmic superhero couldn’t have asked for a better setup than Avengers: Infinity War (Caution — minor spoilers ahead, naturally). Revealed via Nick Fury’s (Samuel L. Jackson) period-inappropriate pager in the end credits, the scene showed off very little in the way of detail, save for the fact that superhuman is apparently the last and best hope for (half) of the universe, yadda, yadda, yadda.

Entertainment Weekly gave us our first real images of Larson as the good Cap’n a few weeks back, and now here we are with the first trailer. The films creators have noted the movie won’t be an origin story proper, though we do seem to have some lost memory to grapple with as we travel back in time a couple of decades prior to Infinity Wars’ events.
