At the 38th minute Julianne Moore playing Havana Segrand experiencing visions of her mother asks John Cusack "Am I a multiple". It's the only popular reference I've seen to reality's dirtiest secret that mind control is used on a wide cross section of prominent society from celebrities, sports stars, Presidents and yeah if you wish assassins and intelligence operatives too. However most mind control is movie and corporate media programming. It's also very effective at that level and easy to prove.
It only gets a mention because Cusack's films are just enough, off the radar to get away with it but I'm grateful for it because each sliver of evidence builds a pointillist picture.
