Continuity mistake: When Howe goes to check Jordan, her eyes are open. After the cut to Vinnie, they're closed.
Other mistake: As the spear mounted on the bucket of the loader passes through the wall, it passes over the body on the bunk. Unless it was a dead body or a dummy, the man should have reacted.
Audio problem: Howe kills the two guys on the sailboat with an M-16, but the sound is of an Uzi.
Revealing mistake: After the machine runs over the terminal, killing him, when the camera shows the legs being run over again, it's easy to tell that they're dummy legs.
Continuity mistake: In the cabin, the survivor and Howe hear an explosion, and the survivor goes out to investigate. He pulls up a board and unlocks the door, and only closes it after him. When the girl comes up from the basement, the door is closed, locked, and barricaded.
