Ken Levine likes this advice to writers from Mike Nichols…
Every scene is either a fight, seduction, or negotiation.
I'm not sure I agree with that. A lot of great movie scenes only have one person in them and it's hard for one person to fight, seduce or negotiate with him or herself. A lot of great movie scenes are end scenes which provide resolution and peace after a lot of fighting, seducing and negotiating.
Which of those three is Julie Andrews singing that the hills are alive with The Sound of Music? Which of those three is the campfire scene in Blazing Saddles? Laurel and Hardy pushing the piano up the stairs? Citizen Kane saying "Rosebud?"
But I'm thinking it's Mike Nichols so he must be right and I'm wrong.
