Man, the casting director for that movie was definitely doing some Stunt Casting, that's an Oof.
Not loving though how the story is presenting "Oh this woman had an affair with a married man and we're gonna put all the blame on her and none on him" I mean, it's accurate to how the court of public opinions treats stories of infidelity, but I hope the story is going to call that out as it goes on.
Just saying, the dude was the one who cheated on his wife and betrayed his family, and it takes two to tango so even if she was the one who initiated it, he would have had to still still willingly participate given the power imbalance in his favour.
And if she wasn't the one who initiated? hoo boy let me tell you about Film Directors cheating on their wives and also coercing sex out of actresses using their position of power in the film industry, because it is a lot.
