Continuity mistake: When Miles jumps off the ferry to swim ashore, the camera view is from the ferry: he jumps into quiet, fairly level water, yet the camera recedes from him (he jumped off the back of the boat as the camera continues moving with the boat). The angle changes and we see the wake of the boat - but it's not what he jumped into.
Continuity mistake: When Rich is held captive in the locked room, he looks out and sees the "Countdown to Landfall" counter at 19min, 51sec. A few minutes later (in plot time), a scientist is seen saying they're now "23 minutes out." (00:11:25 - 00:12:30)
