It all started with Francis Ford Coppola you see... he thought his nephew was so batshit crazy he forced his brother to call him Cage instead. Sofia Coppola has been barred by the family to ever work with him because they now think he's possessed by demons (he is).. which says a lot when you compare him to his brother "The Cope".... who may or not be... Marilyn Manson.
also, Manson was forced to change his name further than even having a C in his last name because he embarrassed Francis so much. I only made up some of that... Cage's brother is literally a radio announcer who goes by "The Cope" and he's the nephew of FFC.
:P
