In film-making as in life certain individuals are given certain roles and when everyone fulfills those roles just right you have a wonderful cut but if one is off it can destroy the whole production. For example it is difficult for the sound engineer to worry about lights and still have the time, energy and skill to do both. Even though the actors might receive much of the accolades any smart performer will realize who is truly behind making them look good.
This is similar to my synagogue which has different roles for men and woman. Although some positions may receive much of the praise those that are truly spiritual will realize the value of each individual person as if they were the screw that held it all together. G-D knows the value of each individuals role in the society we exist in now it’s up to us to recognize it as well.
