I am sure the producers wanted Scarlett Johansson to play the main character because she is a good looking woman. The real life man not so much.
This movie would be a hard sell to middle America with Scarlett Johansson.
Having a “real” man play the part will make it all but impossible.
I predict lots and lots of OSCARS for all involved. /s
But then Hollywood today is making movies for themselves, not for the mass audience.
I dunno. Could they cast Hillary in the role?
