Factual error: Donna jumps off the bridge (which is relatively low down), into shallow water. She then narrowly avoids being hit by a huge ocean liner. There's no way such a huge ship would be in such shallow water - for starters, it couldn't cross under the bridge, being far too big. (00:03:12)
Visible crew/equipment: When Donna jumps off the bridge, her falling body is a dummy/mannequin of some sort - its arms are stiffly by its side, and it has no face. (00:01:54)

Continuity mistake: When Donna jumps off the bridge, it's into relatively shallow water under the bridge, and there is land very nearby (at both ends of the bridge). When the camera shows her in the morning, she is suddenly far out to sea in the ocean. (00:01:51 - 00:09:33)
