Haley's Train Sequence

Haley, did you have any inclination that you were committing perhaps the greatest train sequence committed to film? I remember going into the production meeting and I bought my dogs in. And with that point I was like sure whatever yeah sure I'm gonna whether I like it or not I will be suspended in a vertical train carriage for probably quite a few months here. It sounds like this extraordinary epic set piece that's totally driven by these two characters who by this point are going to be a team working together. Yeah it's really it's really incredible.
