The ship used for the live action pirate scenes in the beginning was the 1960 replica of the HMS Bounty, a merchant ship used by the British Empire in the late 1700s. The replica ship was sunk in late 2012 by Hurricane Sandy. Interestingly enough, a character in the movie (and series) is named Sandy.
This film was intended to be the show's series finale, but due to the success of the film, SpongeBob SquarePants (1999) was then renewed for a fourth season, continuing the series' run. Further episodes of the series were said to take place before this movie.
Spongebob points out that he has been awarded Employee of the Month award 374 times in a row. That would mean that he would have worked at the Krusty Krab for 31 years. This could not happen - according to Stephen Hillenburg, Spongebob was born in 1984, which would mean that, as of 2004, he would only be 20.
