No Experience Necessary!
There's plenty of bizarre occurrences in this movie, but one of the strangest IMO is Duncan Craig being signed on as a first mate on a ship bound for Antarctic waters, despite the fact that he clearly has no commercial sailing experience.
The Scottish captain (don't call me skipper!) seems pretty chilled about it...but second - in - charge in some of the world's most dangerous waters? References clearly weren't called for.
Another one for the only in the movies file.
