would've been interesting if Dane_DeHaan played the male version (spoiler)
I kept thinking the Unwed Mother played by Sarah Snook reminded me of an actor, which I thought was Emma Stone, but really was her spitting-image Dane DeHaan... since there's a he/she thing going on and scenes with split-screen where the actor talks to their crossgendered-counterpart, it would be interesting if she Snook played the female part and DeHaan the male:
