Goofs
Anachronisms
The film begins with Frederic celebrating his 21st birthday, later dating his actual birthday as February 29, 1856, which would make the present year 1877. However, Mabel later remarks that they were living in the 1880s.
Medals on Major General's uniform are from WWII era.
Continuity
After Frederick shuts the Pirate King in the coffin and runs swords through it, the swords completely disappear from the coffin when Frederic lies down in it.
After Mabel and Frederic climb aboard the pirate ship, he is soaking wet but somehow she is dry.
In the scene with Mabel and Frederic stripping before swimming out to the pirates' ship, Frederic is seen taking his shirt completely off. But in the following shot, his shirt is still half-way on.
Crew or equipment visible
The trampoline Mabel uses to mount a horse from behind is clearly visible.
Revealing mistakes
When the Pirate King has his sword at Frederick's throat at the end of the library fight, the safety button on the tip is visible.
When Frederic's scuba-helmet fills with water, he's clearly separated from the water by a thin pane of glass in the front. The helmet's side windows have no sloshing water and it's not dripping from his face as he raises his head to take a breath.
