10 Cloverfield Lane Trailer Breakdown: 15 Clues You Need To See

8. Into The Vents

A couple of shots in the trailer point to an interesting little sequence involving the bunker's vents, something that seems instigated by (shocker) Goodman. Judging by the characters clothes (Winstead is still wearing her T-Shirt), this scene comes before the antagonist-side of Goodman emerges, possibly just before or after the big shake).

And here's Winstead crawling through said vents. There's a whiff of Alien/Die Hard to this (no doubt intentional). These are the only two shots from this sequence, and it's thus hard to deduce what's going on here. I'd bet there's something in there that they're investigating (something that could be alive). Of course, these could be two separate moments - maybe this is her later on, trying to escape.
