Trivia: When Nyah is trying to convince Ethan to shoot her, she says "Do it. Now!" There is still about forty minutes left in the movie, but those are the last words she says.
Trivia: In the movie trailer Tom Cruise greets Ving Rhames when he lands in a helicopter on a remote property in Australia. He says "Welcome to Australia, mate" with an attempted Aussie accent on the word "mate". But that line was never shown in the movie. Not sure why. Perhaps the producers thought that it may come across as Tom mocking Australians?
