Watch a Hollywood screenwriter write a scene from scratch in 7 minutes

Our Boing Boing pal Joe Sabia made a video for Vanity Fair in which he gave screenwriter Emily Carmichael seven minutes to write a scene from a sci-fi thriller from scratch.
It's interesting to hear her thought process as she writes the scene. After she writes it, the scene is critiqued by a studio exec, who gives her notes so she can write a second draft.
Who would have thought a video about someone writing a script would be so much fun?
