Quote examples
Ben Affleck
American Actor
Anxiety is a kind of fuel that activates the fight-or-flight part of the brain in me. It makes sure that a velociraptor isn't around the corner and that you do as much as you possibly can to survive. Because Hollywood has a lot in common with 'Jurassic Park' and its primeval-dinosaur universe.
Quote examples
George C. Wolfe
American Playwright
I love working with a set designer because, in many respects, you meet the set designer before you meet the actors. So it's a chance for me as a director to figure out what I'm thinking and to explore how the space is going to actually be activated.
Quote examples
Matthew Hussey
British Celebrity

Quote examples
Eric Liu
American Writer

Jane Siberry
Canadian Musician

Eve Ensler
American Playwright
