One of the most endearing things I've heard about him was his excitement on John Wick 3 because he was FINALLY able to meet (and work with) Halle Berry because he's been a fan for such a long time! If that isn't one of the sweetest things to hear about a grown man who just seemed so down to Earth, so genuine, so... Just a good person!
This hurts almost as much as when Michael Jackson, Whitney Houston and Robin Williams each passed away. That's my childhood and adulthood in those 3 and someone who I only discovered during Fringe... That shows you the impact he had in a relatively short period of time.
