I love Jodie Foster, and I have to admit that I was nonplussed to discover that she had made a movie with Mel Gibson. It did not seem like a natural pairing. Adorable, lesbian, professional and batshit racist drunk. You can see my confusion.
Then I saw the trailer, and it all became clear.
(Added after the fact.)
I can see where I was misleading. The recordings are of Mel ranting at his wife after they separated, and are taken from her answering machine which she used to tape his calls. Everything that the puppet says in the trailer is what Mel actually said to his wife in reality. The trailer itself is also real, but is unconnected to the phone calls.
