The second week of filming is an exciting time for me as the editor. Why? For two reasons:

1) By now production has gotten into it's stride and is working at full capacity(ish). My organization system has made its changes and now fits the production's needs, including the unexpected ones that pop up at the start.

2) This is usually when we see the appearance of the Ermahgerd Scene. That is a scene that the cast/crew are just DYING to see. A scene with a big special effect, a great dramatic performance between hero and villain, or a killer fight sequence.
