If you're not aware, one of the biggest conflicts in Captain Marvel is the war of two intergalactic alien races: it's the Kree vs. the Skrulls. At one point during filming, it seemed the Kree had captured some Skrull "refugees" and trapped them aboard their ship.
Which brings me to this quote that one crew member yelled while trying to get everyone in their places: "I need all my refugees! This is just a rehearsal, so you don't need your teeth in." Will I ever hear that exact string of words uttered in that order ever again? I highly doubt it.
