Just curious if studios actually have application forms along with minimum requirements or is it really just an arbitrary decision.
I assume you are new to the business and young, therefore I will not make fun of you for this statement
But taken at face value, it's funny, sorry.
Anyway, no, there is no such thing as an application form to direct a studio movie. I see very little data out there to support the idea that the studios use new graduates of any film school as directors. Of course there are thousands of twenty-somethings out there who may believe that a studio chief will see their amazing student film and hire them as a big time studio director. Statistically speaking....not gonna happen.
Yes, there are many factors involved in getting to direct any large scale film financed by the studios. If you can figure them all out let us know, there is no one prescribed course that everyone follows. Many roads up the mountain as they say.
The vast majority of directors these days push their own projects forward with themselves attached as director. This is a process that can take years.
I do know of one guy that came to the attention of the right people via a short film he made, and was given the job of directing a large scale studio movie. He just wrapped production on his second big studio film. So that's one person I know who went that route.
As for the big film schools like USC, yes, they produce a good number of successful people in film. They also have a lot of graduates "flipping burgers" like many other film schools.
