Discussion about Depth and other movies

The woman at the start and the end of the video, who is she?

It's Imogen Reed (the same character you see in the rest of the video, but with longer hair). The parts at the beginning and end of the video seem to be memories/flashbacks showing her life before she found herself in PATHOS-II. You can see the actress (Trin Miller) prepping for those shots here.

EDIT: Ashtoreth just said something to me which I found pretty interesting. What if those aren't flashbacks, but flash-forwards to Imogen living inside the ARK?
