From an interview with Spike Jonze where he relates experiences from his first run-in with big hollywood movie-making: 


“It had slowly, day by day, moved away from what i was trying to do. I didn’t realize how things get corrupted not all in one fell swoop, they get corrupted millimeter by millimeter by millimeter, and only when you look back and see where you were trying to go and where you game from, only then do you really realize how far adrift you’ve gone.”
