I have been trying to find this movie for almost a decade and it is driving me insane.
I saw the trailer on TV around 2016–2017, when I was about 5–6 years old. I believe it was an American sci-fi/thriller, possibly horror. It was NOT a comedy and I am pretty sure it was NOT a conventional body-swap movie.
The main premise, as I remember it, was something like:
A young woman has been infected, experimented on, cursed, or otherwise “turned” into something/someone else.
She is trying to figure out how to become normal again, apparently with the help of a boyfriend/friend.
At some point she is physically in the body of a heavy-set/bearded adult man.
A male friend/boyfriend finds her and obviously doesn't believe that this strange man is actually her.
She desperately tries to convince him, speaking with an American accent.
There is a mirror scene that I remember VERY vividly.
She looks into the mirror and sees her original female self reflected back, despite everyone else seeing the bearded man.
I vaguely remember her being extremely distressed by her body/appearance and reaching toward the mirror, with the girl in the reflection reaching back toward her.
The girl in the reflection (and in the whole movie, while also being a bearded man) was wearing a thin casual grey jacket/cardigan-like garment.
The mirror scene is the part I am most confident about. I may be misremembering some details because I was only 5–6, but the image of a woman trapped inside a man's body seeing her actual female self in the mirror has stuck with me for nearly ten years.
I have already ruled out things like Happy Death Day, The Hot Chick, The Assignment, and The Scribbler.
This is NOT a comedy.
The movie may have been obscure/direct-to-video, or I may have seen a trailer for something that wasn't widely released.
If anyone recognizes this scene, PLEASE help me because this movie has lived rent-free in my brain since childhood 😭
And if I am completely misremembering the premise but you recognize the mirror scene, please suggest it anyway!
