A film director is a person who controls a film's artistic and dramatic aspects and visualizes the screenplay (or script) while guiding the film crew and actors in the fulfillment of that vision. The director has a key role in choosing the cast members, production design and all the creative aspects of filmmaking.
The film director gives direction to the cast and crew and creates an overall vision through which a film eventually becomes realized or noticed. Directors need to be able to mediate differences in creative visions and stay within the budget.
There are many pathways to becoming a film director. Some film directors started as screenwriters, cinematographers, producers, film editors or actors.
