Directors work with the actors during rehearsals to ensure that their vision for the storyline and the finished product is taken into account. The filming process also relies heavily on the director, as they must be happy with the takes before moving onto the next scene in the story. The final phase of a film is post-production, which may take place on or off the set. This is when all of the parts come together to create a final product, and the director will be heavily involved to ensure that the film turns out the way they envisioned.
