Yeah, sorry man, I misread that I guess, but I didn't want our young readers to think that Carruth made that awesome movie without the benefit of some sort of higher education.
Not tangential at all really. Actually the bit about ignoring the failures and holding the rare success up as a beacon of hope is interesting (and dead on accurate), because that's what we all do as artistic types. Director, editor, DoP, even folks who's dream job is to key grip or best boy electric. (Don't laugh, those are valuable and actually difficult jobs that require a great deal of knowledge.) We all have to find some inspiration to keep us moving forward because it is such a war of attrition.
I think though, that it is safe to say there are far more folks who have failed than who have succeeded - regardless of their background coming in. Also, success in this industry isn't always a measure of skill.
Hell, I know a teleprompter operator who just "fell into it" because her neighbor owns a freelance prompter business. She made some remark about how people who try and try and try to get into the business (me, for example) have a harder time than someone who just falls back-ass-wards into it. I just nodded and smiled, and walked off. I work my tail off to get gigs, and then work twice as hard as that once I am there. She was a crappy prompter operator and not a hard worker at all. Lame. So, yeah, you don't need higher education to be in this business. But look around at the absolute jack-wagons working crew who just fell into it because mommy or daddy was someone's hairdresser, or lawyer, or whatever. Same goes for Keys as well. Tons of people out there calling themselves Directors or DoPs that just "fell into it."
Not all of them are hacks - but enough are that it throws off the hypothetical statistics that we don't have available to view.

I want to repeat that. I have actually met a few folks who lucked into a career as crew or keys, and are actually hard working and talented. The point is that this is a business where knowledge, skill, and work ethic are important for success, but not everyone successful got there because they have those traits.
Anyway, it seemed the thread had taken a more "You don't need college." track rather than the film school focus. (examples of Nolan, Carruth, probably some other ones too) I'm always wary of that. Especially when whoever asks the question is in school and considering leaving. Not something to be taken lightly. I believe in a university education, but not as training for a job per se.
As for me, I have a BA in Film, but I do not consider myself as someone who went to "Film School." Totally different experience than going to a film "trade" school like Academy of Art, AI International, NYFA, Expressions, etc. I could have majored in anything, but I wanted to study the history, the theoretical stuff, the language of the art form, things like that.
I'll spare the long, sordid story of me. Suffice to say that I didn't do college right out of high school. I know that even though I haven't reached my goal just yet - I wouldn't be this close had I not gone back to college.
Not because I studied film, but because I got an education.*
* - I also acknowledge that an 'education' does not necessarily have to come from university, but I still believe that the process has value for certain folks.
Double Edit:
Don't know why I am still rambling on this, but here goes:
Personally, I did not start learning to constructively interact with other people until I was in like my mid 20s. Going back to school was a large part of that process. Not everyone needs that sort of social education but I did. I learned things that were missing from my childhood experience by putting myself through college as an adult. I guess that part of it often goes unspoken when folks talk about "to school," or not "to school."
Triple Edit:
Rik, I am in no way shape manner or form referring to you or anyone else on this board when I talk about folks who 'fell into the business.' I've met rock stars and jack wagons from all manner of backgrounds, that paragraph was just 1 part rant, 1 part example, and 1 part tangent. Okay, going to stop talking now.
