Kevin Smith, of Clerks and Dogma fame, got the greenlight to make his movie after only writing six words of the script.

What were the words? The title: "Zack and Miri Make a Porno."

"A bawdy sex comedy with heart," as Smith describes the just-completed script, "Zack and Miri" is about two friends who have managed to trudge into their 30s with a satisfying lack of accomplishment. But a 15-year high school reunion and dire rent problems spark the novel moneymaking idea of pulling together an amateur porn enterprise. As for where it goes from there, just think of Smith's characteristic sexual verbosity finally coupled with matching imagery. (Source)
