Missing is a 1982 American drama film directed by Costa-Gavras, starring Jack Lemmon, Sissy Spacek, Melanie Mayron, John Shea, and Charles Cioffi. It is based on the true story of American journalist Charles Horman, who disappeared in the bloody aftermath of the US-backed Chilean coup of 1973 that deposed the democratically elected socialist President Salvador Allende. The film was jointly awarded the Palme d'Or (with Yol) at the 1982 Cannes Film Festival. Wikipedia
U.S. Ambassador: We're not involved, Mr Horman. Our position has been completely nuetral.
Ed Horman: That is a bald face lie, sir. How can you say a thing like that when you have army colonels, you have naval engineers, they're all over Viña Del Mar!
U.S. Ambassador: Please sit down. Look, it's very obvious you're harbouring some misconception regarding our role here.
Ed Horman: What is your role here? Besides inducing a regime that murders thousands of human beings?
U.S. Ambassador: Let's level with each other, sir. If you hadn't been personally involved in this unfortunate incident, you'd be sitting at home complacent and more or less oblivious to all of this. This mission is pledged to protect American interests, our interests.
Ed Horman: Well, they're not mine.
U.S. Ambassador: There are over three thousand US firms doing business down here. And those are American interests. In other words, your interests. I am concerned with the preservation of a way of life.
Capt. Ray Tower, USN: And a damned good one.
Ed Horman: (Staring out the window) Maybe that's why there's nobody out there.
U.S. Ambassador: You can't have it both ways.
