Factual error: The heroine is trying to get to come on the trip in the minisub. She is asked "Name three under-ice amphopods" The word should be "amphipods", and her answer "Gamamarus" should be "Gammarus". (00:25:30)
Sub Down (1997)
1 factual error - chronological order
Directed by: Gregg Champion
Starring: Stephen Baldwin, Gabrielle Anwar, Tom Conti, Chris Mulkey
Genres: Drama
Continuity mistake: As we see the sub going down, the tech says "descending at 5 ft per second", and another one says "no forward motion". Cut to the sub going forward and down at considerably more than 5 ft per sec and apparently making a rumbling noise while doing it . (00:32:00)
