Research: Blocking A Scene

There are five stages to blocking a scene:

1. Block - Deciding where the actors will be standing and where the camera will be positioned.
2. Light - This is time for the DOP to light the set and position the camera.
3. Rehearse - Time for camera rehearsal of the first set up with the actors and the crew
4. Adjustments - Time for making lighting adjustments and other adjustments needed. 
5. Shoot - Shooting the first scene (repeat the process)

Blocking a scene is simply working out the details of the movements actors make in relation to the camera. You must make sure the actors, crew and camera all move smoothly and harmoniously together. This is often done to create a path for a character and make sure everything fits together. It saves time and ensure everything will play out the way the director wants it to.
