Take a moment to just close your eyes and listen to the world around you. If you are in an office, you probably hear people typing and phones ringing. You might hear the drone of the heater or the air conditioner going on in the background. You hear your coworkers. You hear their footsteps and their conversation about working on a particularly nasty bug.
Making a movie is a never-ending series of compromises, and nothing is as good as the original concept you had in mind. But if you’re really lucky, there’s a moment of alchemy that can happen in the editing room when you put the right piece of music or the right sound effect into the cut. Suddenly something magical happens, and the thing comes to life. You forget about the perfect location you couldn’t secure and the cold your lead actor had on the day you shot the emotional scene. It stops being a maddening litany of disappointments and becomes a movie.
