Real citation: "The documentary is moving forward, but in order to hash out the final details of our agreement I've agreed to meet with a lawyer next week as a means of arbitraton. That's fine, but I'm prepared to walk if things get ugly. Problem is that my momentum is fading a tiny bit -- I like to move faster than this and I can't because it's somebody else's story. I'm used to making short films in a month's time, and the talking-prep stage of this has already taken a month and a half, so I'm going a little itchy-batshitty. Eager to get my finger on the record button."
