Robin Monroe: If you were half a pilot, we wouldn't be on this island!
Quinn Harris: I'm the best damn pilot you're ever going to meet!
Robin Monroe: Ha! I've flown with you twice and you've crashed half the time!
When Robin crashes the plane at the end of the film, it appears that she crashes it about 1/4 mile off shore. But when everyone runs out to the wrecked plane, it's just a few feet from the shoreline.
Temuera Morrison and Cliff Curtis are speaking Maori in their roles as pirates. However they didn't know how to say the complex lines they were supposed to (about gold and pirates, etc), so they just ad-libbed random everyday stuff such as what they were cooking for dinner. (From Temuera's biography "Temuera Morrison: From Haka to Hollywood").
