There are hundreds of film schools across the US. Not all film schools are equal; some film schools are more into production than theory. Before you start searching for a film school, you need to know what kind of skills you want to get out of it. Do you want technical, creative, or a combination of both? Do you want to get into documentary or dramatic filmmaking? Do you want to go into commercial or independent filmmaking? Each school has a focus depending on the philosophy of the faculty who created it. The philosophy of the faculty who created each film school affect the kind of professors who teach the courses. The university or the college select professors who fit the philosophy of the film program. Take for instance, a film school that its focus is on independent filmmaking will employ independent filmmakers as their professors. On the other hand, a film school that its focus is on commercial filmmaking will employ filmmakers who have worked or continue to work on commercial films.
When looking for film schools to attend, you have to do you research about focus of the film school, professors who teach the courses, the type of courses the school offers, and the kind of equipment and facilities that the students have access to and use. You also want to visit the campus, speak with both students and faculty, and tour the facilities. Sometimes what you read is not what is there.
Filmmakers Resource Center has done some of the homework for you. The film schools listed on this site offer production courses in either commercial or independent filmmaking style. You still need to do further research on the film school and pick the one film school that fits the kind of skill sets you want to get out of it. It is very important to visit the campus and make sure that the environment is conducive for you to learn.
