The revelations about Nancy Reagan consulting an astrologer, not a psychic, were revealed at the very end of Reagan's second term. Was Nancy married three times? Did Reagan begin his campaign and then have Nancy reveal that she actually had been married before, but never mentioned it?
Nah. She was just pregnant when they got married.
Both the Reagans dawdled in the unpredictable filmdom world--where Hollyweird studio bosses ruled everyone's life---a place where black is white and white is black.
It seems strange to us, but apparently it is very common for people in that milieu trying to to get film jobs to seek out astrolgers in order to deal with the vagaries of film production, and the unpredictable Hollyweirdos.
