Good interview with Charlie over at the Wall Street Journal. It's largely about Antkind, but Ending Things gets a mention as well. Couple of snippets:
Your new film is adapted from a novel. How did that project come to you?
I was looking for something that somebody would let me direct and it’s easier to get something made if it’s based on a book or a comic book or a movie that’s already existed. The producer I work with happened to have a deal with Netflix. I don’t know that Netflix knew going in that I was going to make it into something that was less of a thriller than the book, and I don’t think I knew that either. The book is leading you to a reveal, and I felt like that might be obvious and disappointing in the movie. Things are more mysterious in words than they are in images.

Was it easier to get an original screenplay made earlier in your career?
Definitely. Earlier in my career, I could play around and experiment, but the business has changed enormously, and it all happened around 2008 when studios stopped making movies and started making tentpoles. The reason something like Netflix attracts filmmakers is because there’s nowhere else to make those things. It’s infuriating to me when people say Netflix is ruining movies because—no, movies ruined movies, studios ruined movies, and that’s the truth. (Source)
