How powerful is Holly Wood? And for what reason?

I do think that Holly Wood has the power to control what sort of film would be made and what is to be included in the film, for example the actors, which is one of the main factors that people may go and watch a film because of their favourite idol or genre, which proves that they have the power yo influence people to watch films in addition Holly wood possess authority because 'On average Holly woods studios make in the region of $25 billion a year globally from movie goers'. which shows the importance of Holly wood in the film industry.

Who/What else is powerful in the film industry?

Holly wood itself is made up of lots of people to make it work, for example the script writers, actors, directors ect. Everyone plays an important role in the film industry, however I believe that audiences have authority over the film industry, for example 'Each year the film industry spends million of dollars researching the cinema goers; they want to know what we like so they can give us more of it'. This shows that we are important as audiences because we are able to effect the making films in the film industry.
