Submarine - the ways in which the candidates’ own experiences of media consumption illustrate wider patterns and trends of audience behaviour.

I think for films like Submarine where you don't need 3D or special effects developments only apply when promoting the film and not in editing or filming of the film. 

As people are not going to cinemas to see films and waiting for the film to be available to stream, download and buy it may stop it may damage Cinema companies meaning that cinemas will not be able to advance in technology.
