Film directors also have the responsibility of handling most of the budgetary concerns of a film, figuring out how to make the movie work on a tight budget. This might involve hiring actors who will work for lower pay, asking family members or friends to help out with some of the behind-the-scenes work, or coming up with less expensive strategies for executing an idea. Film directors are typically under an enormous amount of stress, since they make most of the decisions, and those decisions ultimately determine whether the film will be a success or not. The entire production process of a film can take over a year. The production phase is the busiest and most time-consuming period. The work schedule can vary considerably — for example, ten hours on Monday and then an entirely different set of hours on Tuesday. Working on weekends and evenings is often part of the schedule as well.
