I don't know about Hopkins' personal life, but ISTJ is my impression from interviews. I have a hard time seeing him as ENFJ (compare him to John Cusack, a textbook ENFJ).
I read an interview with Aniston in Elle and it screamed ISTJ...she had crazy accurate Si memory, expressed need for alone time, and had a dry, almost caustic humor. Fe-dom women usually seem much warmer.
