Brie Larson may be better known as Captain Marvel now, but in this comedy (which she directed, co-produced, and stars in), she plays Kit, a unicorn-obsessed art student is given the chance to adopt a unicorn of her very own, thanks to a flamboyantly-dressed sales clerk played by Samuel L. Jackson, and we promise that it's not as weird as it sounds.
