"Delay is natural to a writer. He is like a surfer—he bides his time. Waits for the perfect wave on which to ride in. He waits for the surge (of emotion? of strength? of courage?) that will carry him along." (E.B. White, The Paris Review Interviews, 1969)
Genius lies not in the technique, but in the belief involved.
Adrien Brody, who plays heartthrob writer Jack Driscoll, is known for taking a Method approach to his roles. For The Pianist, he learned how to play Chopin; for The Jacket, he locked himself in isolation tanks until hallucinations set in. Jack Black's method is to sneak Megadeth references into his movies.
