Aldo Ray sits in a hut with natives, trying to find a place for Rita Hayworth in the village. The language used is Samoan. The native says, "Leai se potu," meaning "no room." Ray replies politely but then ends the conversation with, "Alu," which doesn't mean "good-bye" but rather something like, "Get out of here." It's what Samoans say when they shoo animals away from the food or chase children out of the house.
The hotel that W. Somerset Maugham stayed at in American Samoa (the model for Trader Horn's) still stands, but for years has been a general store.
