Nikola Tesla: Mr. Angier, have you considered the cost of such a machine? Robert Angier: Price is not an object. Nikola Tesla: Perhaps not, but have you considered the *cost*? Robert Angier: I'm not sure I follow. Nikola Tesla: Go home. Forget this thing. I can recognize an obsession, no good will come of it. Robert Angier: Why, haven't good come of your obsessions? Nikola Tesla: Well at first. But I followed them too long. I'm their slave... and one day they'll choose to destroy me. Robert Angier: If you understand an obsession then you know you won't change my mind.
