I wouldn’t go that far. Maybe she’s backstabbing her husband. Trump’s family and Trump world is a nest of vipers. If Trump’s life starting in 2015 was made in some kind of reality tv recreation thing - it would probably be 100s of hours of riveting tv. But, no, I have no idea who could play Trump convincingly during all that footage.
Just ~60s or so of secretly filmed footage of her and Trump in private might be fantastic. I can’t even imagine how the two them are to each other in private. Superficially friendly? Icy? Cold as ice? Sarcastic? Openly hostile?
The inevitable book she publishes will be very interesting. I look forward to watching a 10 minute news segment on it before clicking on something else.
