Trivia: The bees in the dome scene are real (there were about 30,000 of them). David Duchovny and Gillian Anderson were actually in the dome with them, and neither of them wore protective gear, but weren't stung nonetheless.
Trivia: In the end credits, an actor is credited as playing Young Ruafo. There are no scenes in the film which this character appears, this is a scene cut from the film, but they forgot to erase the credit. The explanation is that young Ruafo was filmed in the original Insurrection ending, before producers decided on a different (more action based) death for Ruafo and so had him burn on the exploding ship.

(From Temuera's biography "Temuera Morrison: From Haka to Hollywood").
