In an 11.28.16 interview between Carrie Fisher and Fresh Air‘s Terry Gross, Fisher discussed the character of the youngish Harrison Ford, with whom she had an affair during the making of Star Wars (i.e., Episode IV: A New Hope).
Gross noted that Fisher had described Ford in “The Princess Diarist” as “kind of quiet and maybe kind of cold.” Fisher elaborated somewhat:
“Well, he’s not the warmest person. He’s not accessible, let’s say that. He doesn’t talk a lot, and I’m very extroverted. And so that…it sort of was going nowhere. It was sort of one half of a conversation was happening. You know, he’s not a big talker. That’s all. He just…he’s very quiet and chews the side of his mouth a lot.”
