Roles required to make films

In last week's seminar, we learnt about the roles needed to create a film from start to finish. This seminar was a massive eye opener for me in terms of the sheer quantity of people needed for the production and planning of films and it also gave me an insight into what I may want to attempt a career in.
A film crew is made up of numerous roles, some more crucial than others, and these roles share the workload producing a film undertakes.

The main roles are Producer and Director who basically organise and tell everyone what to do and how to do it and they watch over everything that goes on within a production. As you can see in the table above, everyone is made up of different groups and works collaboratively to get the job done quickly and to the best standard possible. My personal aspirations lay in editing as I enjoy how you get to see all the footage in its raw element with no additions to it, and then get to perfect the flow of the film and make its seem like a seamless piece of footage.
