Production Crews: Roles & Responsibilities

Writer

They writer can turn a book into a film through taking the main parts of the book and transferring it into a screenplay to suit a film. They have to take into account that, unlike a book, the words aren't just sentences but have to express character development and personality. Also the fact that the words will be performed as dialogue and so have to convey the story to the audience through what the characters are going to say and do. However if the producer has hired the writer to write the film the producer can ask for rewrites, they my even ask other writers if they don't feel the script is working which happens a lot in big hollywood films. 

Composer 

A composer writes and produces the music for the film but also helps to pick out the non diegetic sounds. For example the bangs and crashes. Their job has a big impact on the emotions in the film as they can control the amount of tension, relaxation, excitement (etc) in scenes. Composers have some responsibility for how the film flows and therefore have to work with the directors in order to place the music in the correct scenes of the film. Finally the composer has to carefully select a team of musicians and editors to put together the different tracks.

Director
The main person in charge of the creativity of the film and how it will be presented to the audience.
During pre production the director casts actors and is able to make changes to the script to suit their personal preference and visions. They will storyboard the shots and choose locations, colour schemes, costumes etc. During production they are in charge of the set and work with the actors and other crew members to ensure their creative ideas are presented in the correct way. 

Head of casting 
They have knowledge of what makes a good actor/actress and what skills are needed, as a result they work with the director to help select the cast members. They look at participants skills, ability and past experience in order to make sure that the perfect people are selected for each role. They are responsible for interviewing and coming up with a fee to offer each cast member.

Producer
They are in charge of co-ordinating the shoot and be responsible for getting anything the film needs to make it happen such as cameras, locations and props. However they don't decide what these things are as the DOB will decide what cameras are needed and the director will decide on the location and the producer just finds these things and negotiate a price.

Camera Operator
They are in charge of filming all the shots in the film and therefore works alongside the director in order to select the correct camera angles, lenses and type of camera. They will have to ensure that all shots are finalised to perfection ensuring the shots take in the full effect of the locations, backdrops and background extras. As a result of this the camera operator also has to work with the director and props crew to make sure the background and props are able to be picked up through a camera.
