I don't personally do that many castings. But I did get involved in "The Bad Batch," because we couldn't think of an actress that was a 3-D embodiment of the character. But when I saw Suki Waterhouse on tape, I knew she was 'it.' And I can't describe that any more than to say that I never had to really express to her the the ideas that were on the page, she just instinctively embraced it. She was Arlen, and I didn't want to f**k it up. Her instinct was just it.
