Corrected entry: When Hopper is being chased by the alien and he goes on deck, Rihanna goes into the control room and aims the cannon at the alien's head. Just before she fires she says "Mahalo" which is thanks in Hawaiian. It would have been better to say "Aloha", which is Hawaiian for hello and goodbye, just before she fires the cannon.

Correction: Not really a mistake, maybe her character doesn't have a grasp of the Hawaiian language, maybe it was a "thanks" because the alien just stared at the deck gun rather than moving slightly to the side to get out of the way. Either way a character saying something different that you wouldn't say isn't a mistake.
