How well do you think they pass?
I happened to see them in The Hunger Games not knowing they were trans, a real test of the old 'transdar'.
They were passing in early scenes, though I did find their face a bit weird in a Tolkein Elf-like manner... as if they were Legolas' younger boyish looking sister.
The bubble burst about half way through with several close ups where their facial features were simply quite large and a bit too masculine for a woman (also I think they had more scenes standing alongside others and it became clear they were tall, by a womans standards, and a bit broad at the shoulders). I began thinking "are they trans?". The illusion was over, finito.
Ultimately they failed to pass for me, though they were doing okay early on. Close but no cigar!
