EG3,
I read your post, and couldn't help but responding, b/c I found myself in a similar position when I was 18, 10 years ago.
My best advice to you is to use your intuition to make a decision. You know whatthe right path for you is. Perhaps you should just think about it more. Journal about your decision, meditate, take a walk and think about it. The answer lies within, not without.
An excellent book I read when I was making this same decision for undergrad was 'Zen and The Art of Making a Living' by Laurence Boldt. Check it out.
All that being said, I would urge you to consider following the communications path instead of the film production route for undergard. That's what I did. I majored in comm. theory at a small liberal arts college, and I couldn't have asked for a better preparation for film. Consider even a major in the liberal arts.
The reason is that the film industry in America is just so oversaturated with people who know the tools, but nothing else. They know the terms for filmmkaking, but they haven't been exposed to the world outisde Amearica, to diverse intellectual ideas, to the creative/spiritual process of making films. That's something a lib. arts education can get you.
Yes, there are also people who are all theory and no practical knowledge. But IMO, it's much easier to acquire the technical or craft knowledge in a couple years of grad school than it is to somehow suddenly develop the human side of your filmmaking in grad school if you haven't done it already through life experiences and the liberal arts.
Undergrad. should be a time for exploring the world - people and ideas, nurturing your creative visions, and opening yourself up to living life. That's what film is all about after all - the communication of authentic human experience.
Many film production majors in undergrad. face the same challenges that many business majors do at the end of their educataions: they know the technicalities of the craft, but haven't played with any other intellectual, socioeconomic, or artistic ideas. In a highly competitive field like filmmaking, interesting ideas are at a premium compared to technical knowlege.
There's some law that says that 90% of everything is crap. Sadly, that goes for student films as well. Even ones that have been labored at for years or are even thesis projects in grad schools. No amount of awards or entries into festivals or prestigious cast or crew can cover up for the simple fact that a film doesn't hit a human chord, doesn't ring emotionally true.
So I guess I would say do play around with the technicalities of directing, editing, cinematography, etc. while in undergrad. But do so in a context where you are learning about the world's people, about history's artistic and intellectual ideas, and about your own creative process.
Good luck!
