One of the most important roles in Inception would be a VFX and general editors. Because the film features a heavy amount of visal effects, and fast cuts to compliment action scenes and to make the film's themes of confusion efective, editors would be important to do this.
The movements on screen, and actions in general, are integral to the film, so a screen writer is essential in making every fight scene and influential motion, such as the spinning top, as poignant as possible.
