The trailer is.. ehr... peculiar, to say the least. The pre-op assasin does not look much like a man, and the post-op assasin just carry on doing what he has always done. In other words: As a crossdreamer fantasy it does not work. Or maybe I am wrong. Let's see.
But as you have said before: This is NOT a movie about a male to female transgender person, and should not be treated as such.
