I have 800 books of just Samuel Beckett's work, tons of his correspondence, personal letters that he wrote. I have copies of plays he used when he directed, so all of his handwritten notes are in the corners of the page.
But even with a character like Cary who is relatively outlandish, at the end of the movie he's in a place where I wouldn't have expected him to be - taking on the responsibility of a woman who is pregnant and who used to be his best friend's wife.
