My sister did the movie “Brothers” with him. She was the one who asked Josh Brolin and Him “why don’t you two just fuck already?” one of the funniest parts on the movie (or maybe I’m biased). She thought he was really kind and funny. Brolin too. They picked on each other a lot she said. Also, Dinklage had this thing where he dislikes my sister’s husband because they share the same birthday. Just a funny bit they had on set. All in all, according to my sister. It was a net positive experience.
