Writers are the most important cog in the film machinery. They are the ones who begin the process by putting pen to paper and writing a story. And once in a while, it all comes together when the writer writes a superb scene, and an equally amazing actor brings it to life. He/She performs the scene exactly or sometimes even better than how the writer, director imagined it.
These monologues need to be treasured since these really embody the power of cinema. It only indicates how Art can overwhelm when done exceedingly well.
