Miiko: if they are discussing "Truman's birthday" then in any case this exchange would not qualify.
There are at least two named women: Meryl, Sylvia and Viviane. None speaks to another. So 1/3.
This movie passed 1 of 3 tests. It was entered by neil on 2008-08-11 15:57:10.
Every single conversation that takes place when Truman isn't on-screen is about Truman, male or female, so while there's no way of arguing this is a 3/3 movie, I would argue that if it was, it would defeat the point of the movie. :p
