If you want to really get in shape and get strong, there's these things called 'sleds.' You take a weighted sled, and you just push it across the floor, and then you drag it back. And, basically, if you do that for 20 minutes a day, you'll look like Arnold Schwarzenegger. If you put enough weight on it, it's the hardest thing in the world.

One of the most beautiful things about Shakespeare's Hamlet is when he stops in the middle of the play to ask, 'To be or not to be?' Then, right at the end, he decides to 'let be.' The first season of 'Stranger Things' was Hopper asking whether 'to be or not to be' and the second is to 'let be.'

I do feel like anything benefits from character logic. That can be from the dumbest ad to the greatest Shakespearean drama to the silliest 'Saturday Night Live' sketch. There is a certain specificity in detail, which you can get when you're paying attention to stuff like that.

I feel like Shakespeare is so epic, in a way that sci-fi genre stuff is epic, it transcends the mundane, and it takes you to this place of real passion and real beauty.

I got the 'Stranger Things' script, like, a week before NBC canceled 'State of Affairs.' I really had this moment where I'm like, 'I'm done.' My neuroses is very sophisticated: I was like, 'I am done. Hollywood is done with David Harbour. They are finished.'
