Things I learned from David Fincher while watching "The Social Network" with no sound:
1. Open the shot on something specific if you can.
2. Let emotional reactions land.
3. Keep it moving.
4. If you have to choose between the film's subject and the frame's subject, keep attention on the former (through camera moves or focus pulls.)
5. Don't neglect inserts and detail shots, even if you can understand what's happening without them.
