This is a very tricky one, to be honest. Virginia is a transvestite early on, but appears to identify herself as female during the end of the film.
If you count conversations between Claire and Virginia, then the film would pass the test. In my opinion, it seems reasonable to classify people who clearly identify themselves as female (I e transgendered) as women for the sake of the test.
The problem is that it's impossible to determine at which point Virginia starts to identify herself as female (rather than male), and thus it's impossible to tell which conversations between them should qualify. It doesn't seem reasonable to count all conversations with Virginia, as early on Virginia is clearly more of a transvestite than transgendered (I e seems to identify him/herself as male).
So either 2 or 3 tests passed, but I don't think anyone except maybe the screenwriters can tell which one is more suitable...
One transvestite character: Virginia
Three men characters: David, Claire husband (named), Liz father (not sure if named).
Claire and Liz have a talk at the hospital about David.
Claire talk with other woman, but they are unnamed (the babysitter, the nurse) or it's about David or Virginia.
Claire and Laura have speechless flashback scene, with Claire off the scene voice.
It did not pass the reverse bechdel test too, David only talk to Claire's husband and liz father. It always about Liz, Claire or the baby girl.
One character is counted twice, to prevent spoiler. It did not chance the result of the test.
The status of Virginia evolve during the movie, it clearly only a transvestite at the beginning and become a transgender woman at the end. Even if you count transgender woman as woman it probably don't change the result of the test.
The gender roles are well balanced in this movie. Technical failure to the test but definitely deserve a pass in my opinion.
